All military personnel are required to receive LOAC training once a year. You must know the ROE's for each deployment you are on, because they determine when and if you may engage the enemy during peacetime or in a conflict. ROE's will also provide a clear transition from peacetime to wartime. All persons directly participating in military operations are considered combatants.
Combatants are proper targets.
All others are noncombatants . This distinction is not always easy to make. Uniformed armed soldiers are easily recognizable. However, guerrillas often mix with civilians, perform undercover operations, and dress in civilian clothes. Alertness and caution must guide you in deciding who is a combatant.
