BASIC PRINCIPLES OF THE LAW OF WAR
William H. Glover, Jr. 1
This Article discusses the restrictions placed upon military members and commanders in the
conduct of operations in both international and non-international armed conflicts. Most of the
material comes from Introduction to the Law of War. Subcourse IS 1805, Edition A,
The Judge Advocate General’s School, U.S. Army, Nonresident Instruction Branch
Charlottesville, Virginia 22903-1781 (February 2002).
The fundamental purposes of the law of war are both humanitarian and functional in nature.
The humanitarian purposes include:
1. Protecting both combatants and noncombatants from unnecessary suffering;
2. Safeguarding the fundamental human rights of persons who fall into the hands of
armed belligerents; and
3. Facilitating the restoration of peace.
The functional purposes include:
1. Preventing the deterioration of good order and discipline in the unit;
2. Maintaining the humanity of the soldiers involved in the conflict; and
3. Maintaining the support of the public for the conflict.
To further the above ends, the Law of War rests on four basic principles:
1. Principle of Military Necessity or Military Objective
This principle states that attacks may be made only against those targets which are valid
military objectives. The definition of military objective is found in Article 52(2) of Protocol I:
Attacks shall be limited strictly to military objectives. In so far as objects are concerned, military
objectives are limited to those objects which by their nature, location, purpose or use make an
effective contribution to military action and whose total or partial destruction, capture or
neutralization, in the circumstances ruling at the time, offers a definite military advantage.
Examples of enemy military objectives which by their nature make an effective contribution to
the military action:
combatants,

armored fighting vehicles,
weapons,
fortifications,
combat aircraft and helicopters,
supply depots of ammunition and petroleum, etc.
Examples of enemy military objectives which by their location make an effective contribution to
the military action:
A narrow mountain pass through which the enemy formation must pass,
bridge over which the enemy’s main supply route (MSR) crosses,
a key road intersection through which the enemy’s reserve will pass, etc.
Examples of enemy military objectives which by their purpose make an effective contribution to
the military action:
Civilian buses or trucks which are being transported to the front to move soldiers from
point A to B,
a factory which is producing ball bearings for the military.
Examples of enemy military objectives which by their use make an effective contribution to
the military action:
An enemy headquarters located in a school,
an enemy supply dump located in a residence, a hotel which is used as billets for
enemy troops. The criterion of use is concerned with the present function of the
object.
Criminal Defense. Military necessity has been urged as a defense to law of war violations, but
generally has been rejected as a defense for acts forbidden by customary and conventional
laws of war. Rationale: laws of war were crafted to include consideration of military necessity.
Look to whether international law allows targeting of a person or property:
Protected Persons. The law of war generally prohibits the intentional targeting of protected
persons under any circumstances.
Protected Places - The Rendulic Rule . The law of war typically allows destruction of civilian
property if military circumstances necessitate such destruction. The circumstances justifying
destruction of protected property are those of “urgent military necessity” as they appear to the
commander at the time of the decision. The Nuremberg Tribunal dismissed charges that
General Lothar Rendulic unlawfully destroyed civilian property via a “scorched earth” policy
2
because “the conditions, as they appeared to the defendant at the time were sufficient upon
which he could honestly conclude that urgent military necessity warranted the decision made.”
Current norms for protection (and destruction) of civilian property : Do not destroy real or
personal property of civilians “except where such destruction is rendered absolutely necessary
by military operations. (GC, art. 53.)
There may be situations where because of poor intelligence or the failure of the enemy to abide
by the law of war, mistakes are made concerning the status of a site: Example: Al Firdus
Bunker. During the Persian Gulf War, planners identified this bunker as a military objective.
Barbed wire surrounded the complex, it was camouflaged, and armed sentries guarded its
entrance and exit points. Unknown to coalition planners, however, Iraqi civilians used the
shelter as nighttime sleeping quarters. The complex was bombed, resulting in 300 civilian
casualties. Was there a violation of the law of war? No. Based on information gathered by
coalition planners, the commander made a reasonable assessment that the target was a
military. Although the attack unfortunately resulted in numerous civilian deaths, there was no
international law violation because the attackers, at the time of the attack, acted reasonably.
Principle of Unnecessary Suffering or Humanity - “It is especially forbidden . . . to employ
arms, projectiles or material calculated to cause unnecessary suffering.” (HR, art. 23e.) This
concept also extends to unnecessary destruction of property. Combatants may not use arms
that are per se calculated to cause unnecessary suffering
projectiles filled with glass, irregularly shaped bullets,
dum-dum rounds,
Principle of Proportionality - The anticipated loss of life and damage to property incidental
to attacks must not be excessive in relation to the concrete and direct military advantage
expected to be gained. (FM 27-10, para. 41, change 1.)
Protocol I . Protection of the civilian population), paragraph 5(b) prohibits “indiscriminate
attacks,” defined in part as an attack where incidental injury to civilians or incidental
damage to civilian objects would be “excessive in relation to the concrete and direct
military advantage anticipated.” The U.S. considers these provisions customary
international law.
Example: During Operation Allied Force, Serbian civilians painted red targets on themselves
and congregated on key bridges over the Danube River. These bridges were military
objectives because they enabled the Serbs to quickly transfer military forces. The Commander
making the targeting decision had to balance the concrete and direct military advantage gained
by destruction of the bridge against the anticipated number of civilian deaths resulting from the
attack.
Incidental Injury and Collateral Damage. Collateral damage consists of unavoidable and
unplanned damage to civilian personnel and property incurred while attacking a military
objective. Incidental (a/k/a collateral) damage is not a violation of international law. However,
3
GP -1 describes indiscriminate attacks as those causing “ incidental loss of civilian life
excessive to the military advantage anticipated.”
Judging Commanders. It may be a grave breach of GP I to launch an attack that a
commander knows will cause excessive incidental damage in relation to the military advantage
gained. The requirement is for a commander to act reasonably. Those who plan or decide
upon an attack, therefore, must take all reasonable steps to ensure not only that the objectives
are identified as military objectives or defended places . . . but also that these objectives may
be attacked without probable losses in lives and damage to property disproportionate to the
military advantage anticipated. (FM 27-10, para. 41.)
In judging a commander's actions one must look at the situation a s the commander saw it in
light of all circumstances. But based on case law and modern applications, the test is not
entirely subjective—“reasonableness” implies an objective element as well. In this regard, two
questions seem relevant.
First, did the commander reasonably gather information to determine whether the target
was a military objective and that the incidental damage would not be disproportionate?
Second, did the commander act reasonably based on the gathered information?
Of course, factors such as time, available staff, and combat conditions affecting the
commander must also weigh in the analysis.
Principle of Discrimination or Distinction. This principle requires that combatants be
distinguished from non-combatants, and that military objectives be distinguished from protected
property or protected places. Parties to a conflict shall direct their operations only against
combatants and military objectives. (GP I, Art. 48) GP I prohibits “ indiscriminate attacks .”
Under Article 51, paragraph 4, these are attacks that: are “not directed against a specific
military objective,” (e.g., Iraqi SCUD missile attacks on Israeli and Saudi cities during the
Persian Gulf War);
might prohibit area bombing in certain populous areas, such as a bombardment “which
treats as a single military objective a number of clearly separated and distinct military
objectives in a city, town, or village
employ a method or means of combat the effects of which cannot be limited as required”
collateral damage excessive in relation to concrete and direct military advantage
APPLICATION OF THE LAW OF WAR
The Law of War applies to all cases of declared war or any other armed conflicts that
arise between the U.S. and other nations,
applies to cases of partial or total occupation. (codified in common article 2 of the
Geneva Conventions).
4
Armed conflicts such as the Falklands War, the Iran-Iraq War, and Desert Storm were
clearly international armed conflicts to which the Law of War applied.
In peace operations, such as those in Somalia, Haiti, and Bosnia, the question frequently arises
whether the Law of War applies to those operations. The issue hinges on whether the peace
operations forces undertake a combatant role. It has thus far been the U.S., UN, and NATO
opinion that their forces have not become combatants, despite carrying out some offensive-
type operations (e.g. Task Force Ranger in Somalia, Operations Deny Flight and Deliberate
Force in Bosnia). Despite the legal inapplicability of the Law of War to these operations, it is,
nonetheless, the position of the U.S., UN, and NATO that their forces will apply the “principles
and spirit” of the Law of War in these operations.
This approach is consistent with DoD policy to comply with the Law of War “in the conduct of
military operations and related activities in armed conflict, however such conflicts are
characterized.” In applying the DoD policy, however, allowance must be made for the fact that
during these operations U .S. Forces often do not have the resources to comply with the Law of
War to the letter. It has been U.S. practice to comply with the Law of War to the extent
“practicable and feasible.”
SOURCES OF THE LAW OF WAR.
The Law of The Hague (ref. (1) and (2)).
Regulates “methods and means” of warfare
prohibitions against using certain weapons such as poison; and humanitarian
concerns such as warning the civilian population before a bombardment.
Geneva Conventions of 1949 (ref. (3) - (6)). The Conventions protect “victims” of war such as
wounded and sick, shipwrecked at sea, prisoners of war, and civilians.
1977 Geneva Protocols Although the U.S. has not ratified GP I and II, judge advocates must
be aware that approximately 150 nations have ratified the Protocols (thus most of the 185
member states of the UN). The Protocols will come into play in most international operations.
U.S. Commanders must be aware that many allied forces are under a legal obligation to comply
with the Protocols. Furthermore, the U.S. considers many of the provisions of the Protocols to
be applicable as customary international law. The impetus for drafting the Protocols was the
International Committee of the Red Cross’ belief that the four Geneva Conventions and the
Hague Regulations insufficiently covered certain areas of warfare in the conflicts following
WWII, specifically
aerial bombardments,
protection of civilians,
and wars of national liberation.
5
New or expanded areas of definition and protection contained in Protocols include
1. provisions for: medical aircraft, wounded and sick, prisoners of war,
2. protections of the natural environment,
3. protections of civilians from indiscriminate attack, and l
4. Legal review of weapons.
The U.S. views some of the GP I articles as either legally binding as customary international
law or acceptable practice though not legally binding:
The U.S. specifically objects to certain articles:
applicability to certain types of armed conflicts
environmental limitations on means and methods of warfare);
limits on the use of enemy flags and insignia);
expansion of definition of combatants,
relaxing of requirement to wear fixed distinctive insignia recognizable at a distance;
(non-protection of mercenaries
Other Treaties. The following treaties restrict specific aspects of warfare:
Geneva Protocol of 1925 prohibits use in war of asphyxiating, poisonous, or other
gases U.S. reserved the right to respond with chemical weapons to a chemical attack by
the enemy.
The Chemical Weapons Convention (CWC), article I(1), prohibits production, stockpiling,
and use (even in retaliation). The U.S. ratified the CWC in April 1997.
The 1954 Hague Cultural Property Convention
prohibits targeting cultural property,
sets forth conditions when cultural property may be used by a defender or attacked.
Although the United States has not ratified the treaty, it does regard its provisions as
relevant to the targeting process:
United States policy and the conduct of operations are entirely consistent with the
Convention’s provisions. In large measure, the practices required by the convention to
protect cultural property were based upon the practices of US military forces during World
War II.”
6
Conventional Weapons (ref. (12)). The 1980 Conventional Weapons Treaty restricts or
prohibits the use of certain weapons deemed to cause unnecessary suffering or to be
indiscriminate:
Protocol I – non-detectable fragments;
Protocol II - mines, booby traps and other devices;
Protocol III - incendiaries; and
Protocol IV - laser weapons. T
The U.S. has ratified the treaty by ratifying Protocols I and II. The Senate is currently
reviewing Protocols III and IV and amendments to Protocol II for its advice and consent to
ratification. The treaty is often referred to as the United Nations Convention on Certain
Conventional Weapons.
Regulations . Implementing LOW guidance for U.S. Armed Forces is found in respective
service regulations. (FM 27-10 (Army), NWP 1-14M/FMFM 1-10 (Navy and Marine Corps), and
AFP AFPD 51-4 (Air Force).)
THE CONDUCT OF HOSTILTIES
Lawful Combatants and Unprivileged Belligerents
Combatants. Anyone engaging in hostilities in an armed conflict on behalf of a party to the
conflict. Combatants are lawful targets unless “out of combat.”
Lawful Combatants. Receive protections of Geneva Conventions, - -gain ”combatant
immunity” for their warlike acts; and become prisoners of war if captured.
Geneva Convention of 1949 Definition. (GPW, art. 4; GWS, art. 13.)
Combatants include: armed forces of a Party to the conflict;
militia,
volunteer corps, and
organized resistance movements belonging to a Party to the conflict that are under
responsible command, wear a fixed distinctive sign recognizable at a distance, carry
their arms openly, and abide by the laws of war; and members of armed forces of a
government not recognized by a detaining authority or occupying power.
Protocol I Definition. Article 43 states that members of the armed forces of a party to the
conflict, except medical personnel and chaplains, are combatants.
7
Article 44(3) of GP I allows that a belligerent attains combatant status by merely carrying his
arms openly during each military engagement, and when visible to an adversary while
deploying for an attack.
Unprivileged belligerents. May be treated as criminals under the domestic law of the captor.
Unprivileged belligerents may include spies, saboteurs, or civilians who are participating in the
hostilities.
Forbidden Conduct with Respect to Enemy Combatants and Nationals
It is especially forbidden to declare that no quarter will be given, or to kill or injure enemy
personnel who have surrendered. H. IV Reg. Art. 23.
It is also forbidden to kill or wound treacherously individuals belonging to the hostile
nation or armed forces.
Belligerents are likewise prohibited to compel nationals of the enemy state to take part
in hostilities against their own country. H. IV art. 23.
Assassination. Hiring assassins, putting a price on the enemy’s head, and offering rewards
for an enemy “dead or alive” is prohibited. (FM 27-10, para 31; E.O. 12333.) Targeting military
leadership, however, is not assassination.
Non-combatants. The law of war prohibits attacks on non-combatants. Among others, non-
combatants include civilians, medical personnel, chaplains, and those out of combat – including
prisoners of war and the wounded and sick.
METHODS AND MEANS OF WARFARE AND WEAPONS
“The rights of belligerents to adopt means of injuring the enemy is not unlimited.” (HR, art. 22.)
Legal Review. All U.S. weapons, weapons systems, and munitions must be reviewed by the
service TJAG for legality under the law of war.
A review occurs before the award of the engineering and manufacturing development contract
and again before the award of the initial production contract. (DoD Instr. 5000.2)
Legal review of new weapons is also required under Article 36 of GP I.
The Test. In the TJAG reviews, the discussion will often focus on whether the suffering
occasioned by the use of the weapon is needless, superfluous, or grossly disproportionate to
the advantage gained by its use.
Weapons may be illegal:
Those weapons calculated to cause unnecessary suffering, determined by the “usage of
states.” Examples: lances with barbed heads, irregularly shaped bullets, projectiles
filled with glass. (FM 27-10, para. 34.)
8
By improper use. Using an otherwise legal weapon in a manner to cause unnecessary
suffering. Example: a conventional air strike against a military objective where civilians are
nearby vs. use of a more precise targeting method that is equally available
By agreement or prohibited by specific treaties. Example: certain land mines, booby traps,
and laser weapons are prohibited under the Protocols to the 1980 Conventional Weapons
Treaty.
Small Arms Projectiles. Must not be exploding or expanding projectiles.
he Declaration of St. Petersburg of 1868 prohibits exploding rounds of less than 400
grams (14 ounces).
Expanding rounds were prohibited by an 1899 Hague Declaration (of which U.S. was
never a party). U.S. practice, however, accedes to this prohibition as being customary
international law.
Hollow point ammunition. Typically, this is semi-jacketed ammunition that is designed to
expand dramatically upon impact. This ammunition is prohibited for use in armed
conflict by customary international law and the treaties mentioned above. There are
situations, however, outside of international armed conflict, where use of this ammunition
is lawful because its use will significantly reduce collateral damage to noncombatants
and protected property (hostage rescue, aircraft security).
High Velocity Small Caliber Arms. Early controversy about M-16 causing unnecessary
suffering due to movement of the high velocity round upon impact. Tests concluded the
rounds did not cause unnecessary suffering.
Sniper rifles, .50 caliber machine guns, and shotguns. Much “mythology” exists about
the lawfulness of these weapon systems. Bottom line: they are lawful weapons,
although rules of engagement (policy and tactics) may limit their use.
Fragmentation. Legal unless used in an illegal manner (on a protected target or in a manner
calculated to cause unnecessary suffering).
Land Mines and Booby Traps. Lawful if properly used, however, international process
underway to outlaw all antipersonnel land mines.
Indiscriminate. Primary legal concern: indiscriminate use that endangers civilian population.
Articles 4 and 5, Protocol II of the 1980 Conventional Weapons Treaty, restrict placement of
mines and booby traps in areas of “civilian concentration.”
Remotely delivered mines (those planted by air, artillery, etc.): Only used against military
objectives; and then only if their location can be accurately recorded and if they are self-
neutralizing or self-destructing.
Non-remotely delivered mines, booby traps, and other devices: May not be used in towns
or cities or other places where concentrations of civilians are present unless: they are placed in
9
the vicinity of a military objective under the control of an adverse party; or measures are in
place to protect civilians from their effects (posting of signs etc.).
Booby Traps: Amended Protocol II of the 1980 Conventional Weapons Treaty also prohibits
use of booby traps
on the dead,
wounded,
Children’s toys,
medical supplies, and
religious objects, among other objects (art. 6).
Requires that all remotely delivered anti-personnel land mines (APL) be equipped with self-
destruct devices and backup self-deactivation features;
(1) Requires that all APL be detectable using available technology;
(2) Requires that the party laying mines assume responsibility to ensure against their
irresponsible or indiscriminate use; and
(3) Provides for means to enforce compliance
U.S. policy on anti-personnel land mines. U.S. forces may no longer employ APL that do
not self-destruct or self-neutralize, (sometimes called “dumb” anti-personnel land mines)
according to a 16 May 1996 policy statement issued by the President. Exceptions to this
policy: the use of non-self-destructing APL on the Korean Peninsula and for training purposes.
U.S. Developments. On 17 September 1997, the President announced the following U.S.
initiatives in regards to anti-personnel land mines:
Develop alternatives to APL by the year 2003;
field them in South Korea by 2006.
Appointed a Presidential advisor on land mines.
Pursue a ban on APL through the UN Conference on Disarmament.
Increase de-mining programs.
Incendiaries. (FM 27-10, para. 36.) Examples:
Napalm, f
lame-throwers,
10
tracer rounds, and
white phosphorous.
None of these are illegal per se or illegal by treaty. The only U.S. policy guidance is found
in paragraph 36 of FM 27-10 which warns that they should “not be used in such a way as to
cause unnecessary suffering.”
Napalm and Flame-throwers. Designed for use against armored vehicles, bunkers, and built-
up emplacements.
White phosphorous. Designed for igniting flammable targets such as fuel, supplies, and
ammunition and for use as a smoke agent.
Protocol III of the 1980 Conventional Weapons Convention. Prohibits use of air-delivered
incendiary weapons on military objectives located within concentrations of civilians.
Has not been ratified by the U.S. The U.S. is currently considering ratifying the protocol - with a
reservation that incendiary weapons may be used within areas of civilian concentrations, if their
use will result in fewer civilian casualties. For example: the use of incendiary weapons against
a chemical munitions factory in a city could cause fewer incidental civilian casualties.
Conventional explosives would probably disperse the chemicals, where incendiary munitions
would burn up the chemicals.
Lasers. U.S. Policy (announced by SECDEF in Sep. 95) prohibits use of lasers specifically
designed, as their sole combat function or as one of their combat functions, to cause
permanent blindness to unenhanced vision.
Chemical Weapons . (FM 27-10, para. 37.) Poison has been outlawed for thousands of years.
Considered a treacherous means of warfare.
The 1925 Geneva Protocol. (FM 27-10, para 38, change 1.) Applies to all international armed
conflicts.
Prohibits use of lethal, incapacitating, and biological agents.
Protocol prohibits use of “asphyxiating, poisonous, or other gases and all analogous
liquids, materials or devices. . . .”
The U.S. considers the 1925 Geneva Protocol as applying to both lethal and incapacitating
chemical agents.
Incapacitating Agents: Those chemical agents producing symptoms that persist for hours
or even days after exposure to the agent has terminated. U.S. views riot control agents as
having a “transient” effect—and thus are NOT incapacitating agents. Therefore, the treaty
does not prohibit their use in war. (Other nations disagree with interpretation.)
11
Under the Geneva Protocol of 1925 the U.S. reserved right to use lethal or incapacitating
gases if the other side uses them first Control Agents: U.S. has an understanding to the
Treaty that these are not prohibited.
Riot Control Agents (RCA). U.S. RCA Policy is found in Executive Order 11850. Applies to
use of Riot Control Agents and Herbicides ; requires presidential approval before first use in an
armed conflict.
EO 11850: renounces first use in armed conflicts except in defensive military modes to save
lives such as:
controlling riots in areas under direct and distinct U.S. military control, to include rioting
prisoners of war;
dispersing civilians where the enemy uses them to mask or screen an attack;
rescue missions for downed pilots/passengers and escaping Paws
n remotely isolated areas; and in our rear echelon areas outside the zone of immediate combat
to protect convoys from civil disturbances, terrorists and paramilitary
1993 Chemical Weapons Convention (CWC) (ref. 9). The CWC was ratified by U.S. and
came into force in April 1997.
Provisions (twenty-four articles).
Article I. Parties agree to never develop, produce, stockpile, transfer, use, or engage in
military preparations to use chemical weapons.
Retaliatory use (second use) not allowed; significant departure from 1925 Geneva
Protocol.
Requires destruction of chemical stockpiles.
Each party agrees not to use Riot Control Agents (RCAs) as a “method of warfare.”
Article II.
Definitions of chemical weapons, toxic chemical, RCA, and purposes not prohibited by
the convention. Article III. Requires parties to declare stocks of chemical weapons and
facilities they possess.
Articles IV and V. Procedures for destruction and verification, including routine on-site
inspections.
RCA Controversy . The Chemical Weapons Convention prohibits RCA use as “method of
warfare.” “Method of warfare” is undefined, however some argue the phrase includes any
actions that involve “combatants” - including traditional hostage rescue/ The rationale for the
12
prohibition - we do not want to give states the opportunity for subterfuge. Keep all chemical
equipment off the battlefield, even if it is supposedly only for use with RCA.
The President’s certification document of 25 April 1997 states that “the United States is not
restricted by the convention in its use of riot control agents in various peacetime and
peacekeeping operations. These are situations in which the U.S. is not engaged in the use of
force of a scope, duration, and intensity that would trigger the laws of war with respect to U.S.
forces.” Thus, during peacekeeping missions (such as Bosnia, Somalia, Rwanda, and Haiti) it
appears U.S. policy will maintain that we are not a party to the conflict for as long as possible.
Therefore RCA would be available for all purposes under E.O. 11850.
However, in armed conflicts (such as Desert Storm, Panama, and Grenada) it is unlikely that
the NCA will approve the use of RCA in situations where “combatants” are involved due to the
CWC’s prohibition on the use of RCA as a “method of warfare.”
Herbicides. E.O. 11850 renounces first use in armed conflicts, except for domestic uses and
to control vegetation around defensive areas. (e.g., Agent Orange in Vietnam.)
Nuclear Weapons. (FM 27-10, para. 35.) Not prohibited by international law.
BOMBARDMENTS, ASSAULTS, AND PROTECTED AREAS AND PROPERTY
Military Objectives. Objects that, by their nature, use, location, or purpose, make an effective
contribution to military action are legitimate military objectives. Their destruction, capture or
neutralization is justified if it offers a definite military advantage. There must be a nexus
between the object and a “definite” advantage toward military operations. Examples: enemy
equipment, munitions factories, roads, bridges, railroads, or electrical powers stations.
Warning Requirement . General requirement to warn before a bombardment . Only applies if
civilians are present. Exception : if it is an assault (any surprise attack or an attack where
surprise is a key element
Defended Places. (FM 27-10, paras. 39 & 40, change 1.) As a general rule, any place the
enemy chooses to defend makes it subject to attack. Defended places include:
a fort or fortified place;
a place occupied by a combatant force or through which a force is passing; and
a city or town that is surrounded by defensive positions under circumstances that the city
or town is indivisible from the defensive positions.
Undefended places. The attack or bombardment of towns, villages, dwellings, or buildings,
which are undefended, is prohibited
Natural environment. The environment cannot be the object of reprisals. In the course of
normal military operations, care must be taken to protect the natural environment against “long-
term, widespread, and severe damage.”
13
Protected Areas. Hospital or safety zones may be established for the protection of the
wounded and sick or civilians. (FM 27-10, para. 45.)
Articles 8 and 11 of the 1954 Hague Cultural Property Convention provide that certain cultural
sites may be designated in an “International Register of Cultural Property under Special
Protections.” The Vatican and art storage areas in Europe have been designated under the
convention as “specially protected.”
Protected Property .
Civilians. Prohibition against attacking civilians or civilian property. (
Presumption of civilian property attaches to objects traditionally associated with civilian use
(dwellings, school, etc.) (GP I, art. 52(3)), as contrasted with military objectives such as
industrial facilities such as munitions factories, which remain legitimate military objectives even
if manned by civilian workers.
Protection of Medical Units and Establishments – Hospitals
Fixed or mobile medical units shall be respected and protected. They shall not be
intentionally attacked. Protection shall not cease, unless they are used to commit “acts
harmful to the enemy.”
Warning requirement before attacking a hospital in which individuals are committing
“acts harmful to the enemy.” The hospital is given a reasonable time to comply with
warning before attack. When receiving fire from a hospital, there is no duty to warn
before returning fire in self-defense. .
Captured Medical Facilities and Supplies of the Armed Forces.
Fixed facilities - May be used by captors for other than medical care, in cases of urgent
military necessity, provided proper arrangements are made for the wounded and sick
who are present.
Mobile facilities - Captors may keep mobile medical facilities, provided they are reserved
for care of the wounded and sick.
Medical Supplies - May not be destroyed.
Medical Transport. Transports of the wounded and sick or medical equipment shall not be
attacked
Cultural Property. Prohibition against attacking cultural property. The convention has not
been ratified by the U.S. Cultural property includes buildings dedicated to religion, art, science,
charitable purposes, historic monuments, hospitals, and places where the sick and wounded
are collected. Misuse will subject them to attack. Enemy has duty to indicate presence of such
buildings with visible and distinctive signs.
14
Works and Installations Containing Dangerous Forces.
The rules are not U.S. law but should be considered because of the pervasive international
acceptance of GP I and II. Under the Protocol, dams, dikes, and nuclear electrical generating
stations shall not be attacked - even if they are military objectives - if the attack will cause the
release of dangerous forces and cause “ severe losses ” among the civilian population. (U.S.
objects to “severe loss” language as creating a different standard than customary
Objects Indispensable to the Survival of the Civilian Population. Article 54 of GP I
prohibits starvation as a method of warfare. It is prohibited to attack, destroy, remove, or
render useless objects indispensable for survival of the civilian population - such as foodstuffs,
crops, livestock, water installations, and irrigation works.
Protective Emblems . (FM 27-10, para. 238.) Objects and personnel displaying emblems are
presumed to be protected under Conventions. (GWS, art. 38.)
Medical and Religious Emblems . Red Cross, Red Crescent, Lion and Sun. Red Star of
David: Not mentioned in the 1949 Geneva Convention, but is protected as a matter of
practice.
Cultural Property Emblems:
“A shield, consisting of a royal blue square, one of the angles of which forms the point of the
shield and of a royal blue triangle above the square, the space on either side being taken up by
a white triangle.” (1954 Cultural Property Convention, art. 16 and 17).
Stratagems and Tactic
Ruses. (FM 27-10, para. 48). Injuring the enemy by legitimate deception (abiding by the law
of war—actions are in good faith). Examples of ruses:
Naval Tactics. A common naval tactic is to rig disguised vessels or dummy ships, e.g.,
to make warships appear as merchant vessels.
Land Warfare. Creation of fictitious units by planting false information, putting up dummy
installations, false radio transmissions, using a small force to simulate a large unit. (FM 27-10,
para. 51.)
Gulf War - Coalition: Coalition forces, specifically XVIII Airborne Corps and VII Corps, used
deception cells to create the impression that they were going to attack near the Kuwaiti boot
heel, as opposed to the “left hook” strategy actually implemented.
Use of Enemy Property. Enemy property may be used to deceive under the following
conditions:
Uniforms. Combatants may wear enemy uniforms but cannot fight in them. Note,
however, that military personnel not wearing their own uniform lose their PW status if
captured and risk being treated as spies.
15
Colors. The U.S. position regarding the use of enemy flags is consistent with its practice
regarding uniforms, i.e., the U.S. interprets the “improper use” of a national flag (HR, art.
23(f).) to permit the use of national colors and insignia of enemy as a ruse Equipment.
Must remove all enemy insignia in order to fight with it. Use of Property . ( See Elyce
Santere, From Confiscation to Contingency Contracting: Property Acquisition on or Near
the Battlefield , 124 Mil. L. Rev. 111 (1989).) Confiscation - permanent taking without
compensation; Seizure - taking with payment or return after the armed conflict;
Requisition - appropriation of private property by occupying force with compensation as
soon as possible; Contribution - a form of taxation under occupation law.
Psychological Operations. Gulf War - U.S. PSYOPS leaflet program - PSYOPS units
distributed over 29 million leaflets to Iraqi forces. The themes of the leaflets were the “futility of
resistance; inevitability of defeat; surrender; desertion and defection; abandonment of
equipment; and blaming the war on Saddam Hussein.” It was estimated that nearly 98% of all
Iraqi prisoners acknowledged having seen a leaflet; 88% said they believed the message; and
70% said the leaflets affected their decision to surrender.
Misuse of Red Cross, Red Crescent, and cultural property symbol. Designed to
reinforce/reaffirm HR, Article 23f. GWS requires that wounded & sick, hospitals, medical
vehicles, and in some cases, medical aircraft be respected and protected. Protection lost if
committing acts harmful to enemy. Cultural property symbols include 1954 Hague Cultural
Property Convention, Roerich Pact, and 1907 Hague Conventions symbol.
Espionage. clandestinely (or on false pretenses) to obtain information for transmission back to
their side. Gathering intelligence while in uniform is not espionage. Espionage is not a law of
war violation. No protection, however, under Geneva Conventions for acts of espionage.
Reprisals. (FM 27-10, para 497.) An otherwise illegal act done in response to a prior illegal
act by the enemy. The purpose of a reprisal is to get the enemy to adhere to the law of war.
Reprisals are authorized if the following requirements are met:
it’s timely;
it’s responsive to enemy’s act;
must first attempt a lesser form of redress; and
The U.S. position is that reprisals are prohibited only when directed against protected
persons as defined in the Geneva Conventions. U.S. policy is that a reprisal may be
ordered only at the highest levels (NCA).
War Trophies. The law of war authorizes the confiscation of enemy military property. War
trophies, as long as taken from enemy military property, are legal under the law of war. The
problem with war trophies arises under U.S. domestic law, rather than under the law of war.
Confiscated enemy military property is property of the U.S. The property becomes a war trophy
—and capable of legal retention by an individual soldier—only if the U.S. so designates the
property IAW law and regulation.
16
The key to a clear and workable war trophy policy is to publicize it before deployment , work it
into all exercises and plans, and train with it! When drafting a war trophy policy, consider the “6
Cs”:
1. COMMON SENSE—does the policy make sense?
2. CLARITY—can it be understood at the lowest level?
3. CI—is the word out through all command information means available? (Post on unit
bulletin boards, post in mess facilities, put in post newspaper, put in PSA on radio, etc.)
4. CONSISTENCY—are we applying the policy across all layers and levels of command? (A
policy promulgated for an entire Corps is better than diverse policies within subordinate
divisions; a policy that is promulgated by the unified command and applies to all of its
components is better still.)
5. CUSTOMS—prepare for customs inspections, “courtesy” inspections prior to redeployment,
and amnesty procedures.
6. CAUTION—Remember one of the prime purposes of a war trophy policy: to limit soldiers
from exposing themselves to danger (in both Panama and the Gulf, soldiers were killed or
seriously injured by exploding ordnance encountered when they were looking for souvenirs).
Consider prohibitions on unauthorized “bunkering, “souvenir hunting,” “climbing in or on enemy
vehicles and equipment.” A good maxim for areas where unexploded ordnance or booby-traps
are problems: “If you didn’t drop it, don’t pick it up.”
Rules of Engagement. Defined: Directives issued by competent superior authority that
delineate the circumstances and limitations under which U.S. forces will initiate and/or continue
engagement with other forces. ROE are drafted in consideration of the Law of War, national
policy, public opinion, and military operational constraints. ROE are often more restrictive than
what the Law of War would allow.
PROTECTED PERSONS
Hors de Combat. Prohibition against attacking enemy personnel who are “ out of combat .”
Prisoners of War. (GPW, art. 4, HR, art. 23c, d.)
Surrender may be made by any means that communicates the intent to give up. No clear-cut
rule as to what constitutes surrender. However, most agree surrender constitutes a cessation
of resistance and placement of one’s self at the discretion of the captor. The onus is on the
person or force surrendering to communicate intent to surrender. Captors must respect (not
attack) and protect (care for) those who surrender—no reprisals. GP I art. 44 expands the
definition of prisoners of war to include any combatant "who falls into the power of an adverse
Party" Combatants include those who do not distinguish themselves from the civilian
population except when carrying arms openly during an engagement and in the deployment
immediately preceding the engagement; e.g., national liberation movements. (GP I, art. 44.)
17
U.S. asserts this definition does not reflect customary international law. Captured civilians
accompanying the force also receive PW status (GPW, art. 4(a)(4)).
Identification and Status. The initial combat phase will likely result in the capture of a wide
array of individuals. 2
The U.S. applies a broad interpretation to the term “international armed
conflict” set forth in common Article 2 of the Conventions. Furthermore, DoD Directive 5100.77,
the DoD Law of War Program, states that U.S. Forces will comply with the LOW regardless of
how the conflict is characterized. Judge advocates, therefore, should advise commanders that,
regardless of the nature of the conflict, all enemy personnel should initially be accorded the
protections of the GPW Convention (GPW), at least until their status may be determined. In
that regard, recall that “status” is a legal term, while “treatment” is descriptive. When drafting or
reviewing guidance to soldiers, ensure that the guidance mandates treatment, not status. For
example, a TACSOP should state that persons who have fallen into the power of U.S. Forces
will be “treated as PW,” not that such persons “will have the status of PW.” When doubt exists
as to whether captured enemy personnel warrant continued PW status, Art. 5 (GPW) Tribunals
must be convened. It is important that judge advocates be prepared for such tribunals. During
the Vietnam conflict, a Directive established procedures for the conduct of Art. 5 Tribunals;
however, no comparable Directive is presently in effect. 3
Treatment. There is a legal obligation to provide adequate food, facilities, and medical aid to
all PWs. This obligation poses significant logistical problems in fast-moving tactical situations;
thus, judge advocates must be aware of how to meet this obligation while placing a minimum
burden on operational assets. 4
PWs must be protected from physical and mental harm. They
must be transported from the combat zone as quickly as circumstances permit. Subject to valid
security reasons, PWs must be allowed to retain possession of their personal property,
protective gear, valuables, and money. These items must not be taken unless properly
receipted for and recorded as required by the GPW. In no event can a PW’s rank insignia or
2
For example, in two days of fighting in Grenada, Army forces captured approximately 450 Cubans and 500 hostile
Grenadians. Panama provided large numbers of detainees, both civilian and "PDF" (Panamanian Defense Force/police force)
for the Army to sort out. The surrender of almost overwhelming numbers of Iraqi forces in the Gulf War was well publicized.
3
No Article 5 Tribunals were conducted in Grenada or Panama, as all captured enemy personnel were repatriated as soon as
possible. In the Gulf War, Operation DESERT STORM netted a large number of persons thought to be EPWs, who were
actually displaced civilians. Subsequent interrogations determined that they had taken no hostile action against Coalition
Forces. In some cases, they had surrendered to Coalition Forces to receive food and water. Tribunals were conducted to
verify the status of the detainees. Upon determination that they were civilians who had taken no part in hostilities, they were
transferred to detainment camps. Whether the tribunals were necessary as a matter of law is open to debate -- the civilians had
not "committed a belligerent act," nor was their status "in doubt."
4
The following examples are illustrative. When U.S. Forces landed in Grenada, they did not possess the food necessary to
feed the large number of PWs and detainees who would come under our control. Thus, we used captured foodstuffs to feed
them. Similar situations occurred in Panama. Thus, by using captured food, the U.S. met its obligation under the GPW, and
the ground commanders were able to conserve valuable assets. Initially, PW facilities on Grenada, in Panama, and in the Gulf
were each inadequate in their own ways. They consisted of dilapidated buildings, with no sanitation facilities or electricity, or
were simply non-existent (in the desert). The ground commanders could not afford to use critically needed combat personnel
(the personnel necessary to handle PWs were not initially available) to construct PW camps. Because the LOW does not
require combatants to use their own assets to construct PW camps, the U.S. used captured property and PWs to construct
adequate camps. (In fact, in Grenada the PWs were Cuban construction workers.). Medical assets also tend to be in high
demand and short supply during combat. The LOW, however, prohibits the willful denial of needed medical assistance to PWs,
and priority of treatment must be based on medical reasons. While the Capturing Party has the obligation to ensure adequate
medical care for enemy wounded, the GWS Convention encourages the use of "retained persons" to treat enemy wounded.
The U.S. has made use of this provision as well. As these examples indicate, the JA must be familiar with and apply the LOW
in a practical manner. In doing so, he enables the commander to comply with legal requirements, without jeopardizing the
mission.
18
identification cards be taken. These protections continue through all stages of captivity,
including interrogation.
Detainees. Particularly in Military Operations Other Than War, where there are no lawful
enemy combatants (e.g., Somalia, Haiti, Bosnia, as discussed above), persons who commit
hostile acts against U.S. forces or serious criminal acts and are captured do not meet the legal
criteria of PW under the GPW. These persons may be termed “detainees” instead of PW.
Wounded and Sick in the Field and at Sea. (GWS, art. 12; GWS Sea, art. 12.)
The first and second Geneva Conventions as well as the 1977 Protocol I to the Geneva
Conventions deal with protections for the wounded and sick, to include the shipwrecked.
All wounded and sick in the hands of the enemy must be respected and protected ( See para.
208, FM 27-10, GWS Art 13, and GC, Art 16). “Each belligerent must treat his fallen
adversaries as he would the wounded of his own army” (Pictet’s Commentary, GWS, p. 137).
The order of treatment is determined solely by urgent medical reasons (triage). No adverse
distinctions in treatment may be established because of sex, race, nationality, religion, political
opinions, or any other similar criteria (GWS, Art 12).
If compelled to abandon the wounded and sick to the enemy, commanders must leave medical
personnel and material to assist in their care, “as far as military considerations permit” (GWS,
Art 12). At all times, and particularly after an engagement parties are obligated to search for
the wounded and sick - as conditions permit (GWS, Art 15).
Permanent medical personnel “exclusively engaged” in medical duties (GWS, Art 24),
chaplains (GWS, Art 24), personnel of national Red Cross Societies, and other recognized
relief organizations (GWS, Art 26), shall not be intentionally attacked. Upon capture they are
“retained personnel,” not PWs; however, at a minimum they receive PW protections. They are
to perform only medical or religious duties. They are to be retained as long as required to treat
the health and spiritual needs of PWs. If not required they are to be repatriated (GWS, Art 28).
Personnel of aid societies of neutral countries cannot be retained, and must be returned as
soon as possible.
Medical units and establishments may not be attacked. ( GWS, Art 19). However, incidental
damage to medical facilities situated near military objectives is not a violation of the law of war.
Medical units and facilities lose their protection if committing “acts harmful to the enemy,” and, if
after a reasonable time, they fail to heed a warning to desist. No warning requirement if taking
fire from the medical unit or establishment; e.g., Richmond Hills Hospital, Grenada (GWS, Art
21, Pictet’s Commentary on GWS, pp. 200-201).
Those soldiers who have fallen by reason of sickness or wounds and who cease to fight
are to be respected and protected. Under GP I, civilians are included in the definition of
wounded and sick (who because of trauma, disease, . . . are in need of medical assistance and
care and who refrain from any act of hostility). (GP I, art. 8.) As a practical matter, care should
be provided to civilians if medical resources are available. Otherwise, civilian care remains the
primary responsibility of the civilian authorities.
19
Shipwrecked members of the armed forces at sea are to be respected and protected .
(GWS Sea, art. 12, NWP 1-14M, para. 11.6). Shipwrecked includes downed passengers/crews
on aircraft, ships in peril, castaways.
Parachutists (FM 27-10, supra , para. 30). Descending paratroopers are presumed to be on a
military mission and therefore may be targeted. Parachutists are crewmen of a disabled
aircraft. They are presumed to be out of combat and may not be targeted unless it is apparent
they are engaged on a hostile mission. Parachutists, according to GP I, Article 42, “shall be
given the opportunity to surrender before being made the object of attack.”
Civilians.
General Rule . Civilians and civilian property may not be the subject or sole object of a military
attack. Civilians are persons who are not members of the enemy’s armed forces, and who do
not take part in the hostilities (GP I, art. 50 and 51).
Indiscriminate Attacks. GP I provides for expanded protections of the civilian population from
“indiscriminate” attacks. Indiscriminate attacks include those where the incidental loss of
civilian life, or damage to civilian objects, would be excessive in relation to the concrete and
direct military advantage anticipated. (GP I, art. 51(4).)
Civilian Medical and Religious Personnel. Article 15 of GP I requires that civilian medical and
religious personnel shall be respected and protected. They receive the benefits of the
provisions of the Geneva Conventions and the Protocols concerning the protection and
identification of medical personnel. All available help shall be given to civilian medical
personnel when civilian services are disrupted due to combat.
Personnel Engaged in the Protection of Cultural Property. Article 17 of the 1954 Hague
Cultural Property Convention established a duty to respect (not directly attack) persons
engaged in the protection of cultural property. The regulations attached to the Convention
provide for specific positions as cultural protectors and for their identification.
Journalists. Given protection as “civilians” provided they take no action adversely affecting
their status as civilians. (GP I, art. 79 - considered customary international law by U.S.).
MILITARY OCCUPATION
The Nature of Military Occupation
Territory is considered occupied when it is actually placed under the authority of the hostile
armed forces. The occupation extends only to territory where such authority has been
established and can effectively be exercised. H. IV Regs. Art. 42. Thus, occupation is a
question of fact based on the invader's ability to render the invaded government incapable of
exercising public authority. Simply put, occupation must be both actual and effective. (FM 27-
10, para. 352) However, military occupation (also termed belligerent occupation) is not
conquest; it does not involve a transfer of sovereignty to the occupying force. Indeed, it is
unlawful for a belligerent occupant to annex occupied territory or to create a new state therein
while hostilities are still in progress. See GC, art. 47. It is also forbidden to compel the
20
inhabitants of occupied territory to swear allegiance to the hostile occupying power. H IV.
Regs. Art. 45. Occupation is thus provisional in nature, and is terminated if the occupying
power is driven out.
Administration of Occupied Territory
Occupied territory is administered by military government, due to the inability of the legitimate
government to exercise its functions, or the undesirability of allowing it to do so. The occupying
power therefore bears a legal duty to restore and maintain public order and safety, while
respecting, "unless absolutely prevented," the laws of the occupied nation. H. IV. Regs Art. 43.
The occupying power may allow the local authorities to exercise some or all of their normal
governmental functions, subject to the paramount authority of the occupant. The source of the
occupant's authority is its imposition of government by force, and the legality of its actions is
determined by the Law of War.
In restoring public order and safety, the occupant is required to continue in force the normal
civil and criminal laws of the occupied nation, unless they would jeopardize the security of the
occupying force or create obstacles to application of the GC. See GC Art. 64. However, the
military and civilian personnel of the occupying power remain immune from the jurisdiction of
local law enforcement.
Articles 46-63 of the GC establish important fundamental protections and benefits for the
civilian population in occupied territory. Family honor, life and property, and religious
convictions must be respected. Individual or mass forcible deportations of protected persons
from the occupied territory to the territory of the occupying power or to a third state are
prohibited. GC Art. 49. The occupying power has the duty of ensuring that the population is
provided with adequate food, medical supplies and treatment facilities, hygiene, and public
health measures. GC Art. 55. In addition, children are subject to special protection and care,
particularly with respect to their education, food, medical care, and protection against the
effects of war. GC Art. 50.
The occupying power is forbidden from destroying or seizing enemy property unless such
action is "imperatively demanded by the necessities of war," H. IV. Regs. Art. 23, or "rendered
absolutely necessary by military operations." GC Art. 53. "Pillage is formally forbidden." H. IV.
Regs. Art. 47. However, the occupying power may requisition goods and services from the
local populace to sustain the needs of the occupying force, "in proportion to the resources of
the country, and of such a nature as not to involve the population in the obligation of taking part
in operations of the war against their country." The occupying power is obliged to pay cash for
such requisitions or provide a receipt and make payment as soon as possible. H. IV. Regs. Art.
52.
The occupying power may not compel protected persons to serve in its armed forces, nor may
it compel them to work unless they are over eighteen years old, and then only on work that: (1)
is necessary for the needs of the occupying force; (2) is necessary for public utility services; or
(3) for the feeding, sheltering, clothing, transportation or health of the populace of the occupied
country. The occupied country's labor laws regarding such matters as wages, hours, and
21
compensation for occupational accidents and diseases remain applicable to the protected
persons assigned to work by the occupant. GC Art. 51; see H. IV. Regs. Art. 23.
The occupying power is specifically prohibited from forcing the inhabitants to take part in
military operations against their own country, and this precludes requiring their services in work
directly promoting the military efforts of the occupying force, such as construction of
fortifications, entrenchments, and military airfields. See GC Art. 51. However, the inhabitants
may be employed voluntarily in such activities.
Security of the Occupying Force: Penal Law and Procedure
The occupant is authorized to demand and enforce the populace's obedience as necessary for
the security of the occupying forces, the maintenance of law and order, and the proper
administration of the country. The inhabitants are obliged to behave peaceably and take no
part in hostilities.
If the occupant considers it necessary, as a matter of imperative security needs, it may assign
protected persons to specific residences or internment camps. GC Art. 78. The occupying
power may also enact penal law provisions, but these may not come into force until they have
been published and otherwise brought to the knowledge of the inhabitants in their own
language. Penal provisions shall not have retroactive effect. GC Art. 65.
The occupying power's tribunals may not impose sentences for violation of penal laws until
after a regular trial. The accused person must be informed in writing in his own language of the
charges against him, and is entitled to the assistance of counsel at trial, to present evidence
and call witnesses, and to be assisted by an interpreter. The occupying power shall notify the
protecting power of all penal proceedings it institutes in occupied territory. Sentences shall be
proportionate to the offense committed. The accused, if convicted, shall have a right to appeal
under the provisions of the tribunal's procedures or, if no appeal is provided for, he is entitled to
petition against his conviction and sentence to the competent authority of the occupying power.
GC, Arts. 72, 73.
Under the provisions of the GC, the occupying power may impose the death penalty on a
protected person only if found guilty of espionage or serious acts of sabotage directed against
the occupying power, or of intentional offenses causing the death of one or more persons,
provided that such offenses were punishable by death under the law of the occupied territory in
force before the occupation began. GC Art. 68. However, the United States has reserved the
right to impose the death penalty for such offenses resulting in homicide irrespective of whether
such offenses were previously capital offenses under the law of the occupied state. In any
case, the death penalty may not be imposed by the occupying power on any protected person
who was under the age of eighteen years at the time of the offense. GC Art. 68.
The occupying power must promptly notify the protecting power of any sentence of death or
imprisonment for two years or more, and no death sentence may be carried out until at least six
months after such notification. GC Arts. 74, 75.
The occupying power is prohibited from imposing mass punishments on the populace for the
offenses of individuals. That is, "No general penalty, pecuniary or otherwise, shall be inflicted
22
upon the populations on account of the acts of individuals for which they cannot be regarded as
jointly and severally responsible." H. IV. Regs Art. 50; see GC, Art. 33.
In areas occupied by United States forces, military jurisdiction over individuals, other than
members of the U.S. armed forces, is exercised by courts of the military government. Although
sometimes designated by other names, these military tribunals are actually military
commissions. They preside in and for the occupied territory and thus exercise their jurisdiction
on a territorial basis.
NEUTRALITY
Customary Law Reflected in Hague Convention No. V
Under customary international law, as reflected in Hague Convention No. V, neutrality on the
part of a state not a party to an armed conflict consists in refraining from all participation in the
conflict, and in preventing, tolerating, and regulating certain acts on its own part, by its
nationals, and by the belligerents. In response, it is the duty of the belligerents to respect the
territory and rights of neutral states. Those neutrality rights include the following:
The territory of the neutral state is inviolable. H. V. Art. 1. This prohibits any unauthorized
entry into the territory of the neutral state, its territorial waters, or the airspace over such areas
by troops or instrumentalities of war. Thus, belligerents are also specifically prohibited from
moving troops or convoys of war munitions or supplies across the territory of a neutral state. H.
V. Art. 2. In consequence, the efforts of the neutral to resist, even by force, attempts to violate
its territory cannot be regarded as hostile acts by the offending belligerents. H. V. Art. 10.
However, if the neutral is unable, or fails to prevent such violations of its neutrality by the troops
of one belligerent, that belligerent's enemy may be justified in attacking those troops in neutral
territory.
Belligerents are also prohibited from establishing radio communications stations in neutral
territory to communicate with their armed forces, or from using such facilities previously
established before the outbreak of hostilities for that purpose. H. V. Art. 3. However, a neutral
state may permit the use of its own communications facilities to transmit messages on behalf of
the belligerents, so long as such usage does not lend assistance to the forces of only one side
of the conflict. Indeed, the neutral must ensure that the measure it takes in its status as a
neutral state are impartial as applied to all belligerents. H.V. Art. 9.
While a neutral state is under no obligation to allow passage of convoys or aircraft carrying the
sick and wounded of belligerents through its territory or airspace, it may do so without forfeiting
its neutral status. However, the neutral must exercise necessary control or restrictive
measures concerning the convoys or medical aircraft, must ensure that neither personnel nor
material other than that necessary for the care of the sick and wounded is carried, and must
accord the belligerents impartial treatment. H. V. Art. 14; see GWS Art. 37. In particular, if the
wounded and sick or prisoners of war are brought into neutral territory by their captor, they
must be detained and interned by the neutral state so as to prevent them from taking part in
further hostilities. GWS Art. 37.
23
The nationals of a neutral state are also considered as neutrals. H. V. Art. 16. However, if
such neutrals reside in occupied territory during the conflict, they are not entitled to claims
different treatment, in general, from that accorded the other inhabitants. They are likewise
obliged to refrain from participation in hostilities, and must observe the rules of the occupying
power. Moreover, such neutral residents of occupied territory may be punished by the
occupying power for penal offenses to the same extent as nationals of the occupied nation.
See GC Art. 4.
A national of a neutral state forfeits his neutral status if he commits hostile acts against a
belligerent, or commits acts in favor of a belligerent, such as enlisting in its armed forces.
However, he is not to be more severely treated by the belligerent against whom he has
abandoned his neutrality than would be a national of the enemy state for the same acts. H. V.
Art. 17.
The United States has supplemented the ab
