UNSC Judge Advocate General's Corps

The UNSC Judge Advocate General's Corps (JAG) is an 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. JAG officers are also sent to investigate crimes involving the UNSC on human colonies; for example, Major Ira Halal was sent to investigate a series of murders on Gao and to ensure that anti-Unified Earth Government radicals on the planet did not plant false evidence on the crime scenes to frame the UNSC for the murders.

Among the other responsibilities of the JAG Corps is the issuing of various protocols that stipulate punishments for offenses. 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.
