A military member can be arrested and charged by the civil authorities as well as courts martial procedures. This is not deemed double jeopardy under concurrent jurisdiction, UCMJ and RCM, Rules for Courts Martial under the Manual for Courts Martial, I believe Rule 302(b). This same Rule, and Art 7b, UCMJ gives military police the right to detain and/or apprehend. It also allows for the military member to face charges both civillay and in the military. Usually the civil court will let the military handle the charges.
