Terran Colonial Authority

The Terran Colonial Authority or TCA is a police force that operates in human space. It is called upon in cases that do not immediately require military assistance. The TCA may be an offshout of the New Earth Government.

Although the exact date the TCA was formed is unknown, the earliest known reference was made in 2241 at the end of the Strider Wars. This is the time period before Unreal 2. The TCA is still around in 2303, the time period of Unreal Tournament 2004.

TCA authority is divided up into jurisdictional sectors, some better staffed, and some seeing more action than others.

During the time period of Unreal 2 Sector Commander Hawkins is the highest ranking official in an outskirts sector, which includes planets such as: Sanctuary, Hell, Janus, and the sector's headquarters, Avalon. The game centers around John Dalton, a TCA Marshall, and his crew aboard the TCA Atlantis, who operated in the sector. This crew played a primary role in the incident concerning ancient Artifacts.

Before fighting in the Tournament, Metal Guard's Karag was a TCA Marshall.
