Answer:
laws that apply to those serving in the armed forces and to civilians who work for the armed forces
Explanation:
Military law is a body of law that is concerned about maintaining the discipline of a nation's armed forces. This also applies to civilians who'd like to work for the armed forces and this is called the "Army Civilian Forces." It also encompasses citizen-soldiers who are working in both careers (military and non-military). They are called "military reserve forces." They undergo training in congruence to the laws made for the military.
Military law has to be differentiated from "martial law." Martial law is the body of law that is used in order to govern a state or nation in times of war or emergency.
Thus, this explains the answer.
