The FBI’s most elite tactical teams make up The Tactical Section of the FBI’s Critical Incident Response Group (CIRG). These include the Crisis Negotiation Unit (CNU), Special Weapons and Tactics (SWAT), Hostage Rescue Team (HRT) and others. The operatives in these units are as skilled as Army Rangers and Navy Seals from their extensive combat training, expected speed and stamina. The FBI Tactical Operation Section was put together in 1982, and since then has carried out over 850 missions.

The Tactical Section, as well as addressing terrorism and other crimes, leads the FBI in undercover operations, hostage negotiations, high-risk pursuits and surveillance operations in the United States and overseas. Officers in the Tactical Section are also charged with the safety of FBI staff in live combat zones including Afghanistan and Iraq, and in carrying out rescue operations following natural disasters. Because of this, Tactical Section are required to be available 24/7, and must train all year with the military Special Forces.
