UNSC Judge Advocate General's Corps

The Judge Advocate General's Corps (JAG) is a organization of the United Nations Space Command concerned with legal matters. JAG officers also serve in courts-martial or on boards of inquiry. Captain Maria Gilliam was one such officer in 2492 at the Luna OCS Academy.

Among the other responsibilities of the JAG Corps is the issuing of various protocols that stipulate punishments for offences. Some of these punishments can be quite draconian. The JAG 845-P protocol authorizes the imprisonment for life or execution without a proper trial of offenders who commit treason or violate the Cole Protocol.
