Usage notes 
The term 'enemy combatant' has historically referred to any member of the armed forces of a state with which another state is at war. In the 'war on terrorism', however, combatants may come from multiple nations, wear no uniforms, and use unconventional weapons; because they are not defined by simple, readily apparent criteria such as citizenship or military uniforms, the power of a state to name people 'enemy combatants' is, according to some legal scholars, extraordinarily broad.
