TAC team

The Counter Terrorist Unit employs teams of elite field agents called TAC teams. It is presumed that TAC stands for Tactical Assault Commandos. They are CTU's rough equivalent of the FBI's Hostage Rescue Team and police SWAT teams. TAC teams have assisted Jack Bauer on many occasions, and have been a valuable asset in CTU's efforts fighting terrorists.

TAC team members are presumably highly trained in all aspects of CRW(Counter-Revolutionary Warfare) techniques and skills including building assault, sniping, Close Quarter Battle, the many aspects of marksmanship, sentry removal, offensive and defensive driving, demolitions, and the execution of hostage rescue missions, as well as how to operate in both urban and non-urban terrain, and the use of a variety of weapons.
