The mission of BORTAC is "to respond to terrorist threats of all types anywhere in the world in order to protect our nation’s homeland." 
The unit was first formed in 1984 to deal with disturbances occurring within INS detention facilities, but this mission is now handled by ICE, Enforcement & Removal Operations (ERO), Special Response Teams (SRT). Since its inception BORTAC has steadily expanded its scope and mission capabilities, and is now a rapid response unit capable of executing both foreign and national level domestic operations. BORTAC members have operated in 28 countries around the world. Missions have included international training/advisory functions, counter terrorism operations, counter narcotics operations, high-risk warrant service, dignitary protection, interdiction & patrol operations, and tactical training to other U.S. agencies and military units.
BORTAC headquarters is co-located with its training unit at Biggs Army Airfield, Fort Bliss in El Paso, Texas. The BORTAC training unit is currently responsible for conducting all CBP tactical team training. In addition, the unit also provides specialist training to other Federal, state and local law enforcement agencies. As part of a joint Department of State/ Department of Justice training program, BORTAC has also provided tactical team and counter narcotics training to several foreign governments police, paramilitary, tactical, drug, and specialist units, including the El Salvador National Police's Grupo de Respuesta Policial (GRP) tactical unit.

Each team member is also equipped with a Kevlar ballistic helmet and a Kevlar assault vest. Boots worn by individual team members depend on the operator's personal preference and situation.
Following the World Trade Center Attack in September 2001, BORTAC personnel were sent to high-risk areas around the country to help secure against future attacks.
Recent natural disasters have vaulted BORTAC personnel into tactical relief operations (TRO) by providing hurricane relief aid to Gulf Coast residents and law enforcement support to law enforcement agencies affected by Hurricane Katrina.
