Which groups are described as lawful combatants?

• A. Members of armed forces
• B. Militia/volunteer corps that belong to the state
• C. Inhabitants participating in uprising
• D. All of the above

Answer: (D)

The concept being tested is who can have combatant status under international humanitarian law. Combatant status isn’t limited to regular soldiers; it extends to groups that are part of a party to the conflict and meet certain criteria, because they operate as organized forces within the conflict and are subject to the laws of war.

Members of armed forces obviously fit: they are the organized military component of the state and fight under lawful command and discipline.

Militia or volunteer corps that belong to the state can also be lawful combatants, provided they act as part of the armed forces, are under responsible command, wear a distinctive sign, carry arms openly, and conduct themselves according to the laws of war.

Inhabitants participating in an uprising can likewise be lawful combatants if they form an organized, identifiable force that is under a command structure and belongs to a party to the conflict, thereby meeting the same conditions as other armed groups. If they do not meet those conditions, they remain civilians or fall into other categories.

Since each of these groups can qualify as lawful combatants under the right conditions, the best answer is that all of them can be described as lawful combatants.
