A civilian is any person who does not belong to any of the following categories: members of the armed forces, militias or volunteer corps, organized resistance movements,
and residents of an occupied territory who spontaneously take up arms. If there is any doubt whether a person is civilian, then he or she is to be considered a civilian. (Protocol I, Art. 50, Sec. 1)
civilian population
The civilian population comprises all persons who are civilians. (Protocol I, Art. 50, Sec. 2)
The civilian population is protected under the Geneva Conventions and these protections are not affected by the presence of combatants in the population. (Protocol I, Art. 50, Sec. 3)
combatant status
Combatants have protections under the Geneva Conventions, as well as obligations.
Convention I offers protections to wounded combatants, who are defined as members of the armed forces of a party to an international conflict, members of militias or volunteer corps including members of organized resistance movements as long as they have a well-defined chain of command, are clearly distinguishable from the civilian population, carry their arms openly, and obey the laws of war. (Convention I, Art. 13, Sec. 1 and Sec. 2)
~snip
However, other individuals, including civilians, who commit hostile acts and are captured do not have these protections. For example,
civilians in an occupied territory are subject to the existing penal laws. (Convention IV, Art. 64)"
seems clear to me..you are either a combatant and protected by the convention or you are a civilian subject to EXISTING penal laws
