A Tactical Operations Center (abbreviated "TOC"), is a mobile command center used for conducting ground operations. UNSC corvettes have a TOC located on board, which contains equipment for reconnaissance, communication, and command-and-control for units operating on the ground. Commanding officers of larger units sometimes command special operations from a TOC, as do ONI field operatives.[1]

One such TOC was on the UNSC Bum Rush, and was used as a command center for the battalion of Marines operating on Tribute as part of Operation: TREBUCHET in 2524.
