"The United States Border Patrol (USBP) created the Border Patrol Search, Trauma, and Rescue (BORSTAR) Unit in 1998 in response to the growing number of injuries to Border Patrol agents and migrant deaths along our Nation's borders. BORSTAR is located at the USBP's Special Operations Group Headquarters in El Paso, Texas, and among USBP sectors. BORSTAR provides specialized law enforcement, search and rescue response from conventional to high-risk Border Patrol Operations, Federal Emergency Management Agency mission assignments, national search and rescue operations, national special security events, and specialized training support that DHS directs for both domestic and foreign government agencies. BORSTAR is the only national law enforcement search and rescue entity with the capability to conduct tactical medical and search and rescue operations, and training for federal, state, local, and international government agencies. Since the inception of BORSTAR in 1998, the unit has evolved and enhanced its capabilities to fulfill the missions of DHS, U.S. Customs and Border Protection (CBP), and USBP, both foreign and domestic. [...] The BORSTAR Selection and Training Course is a physically and mentally demanding course in which candidates are evaluated in various search and rescue techniques, tactical medicine, technical rescue, land navigation, communication, swift-water rescue, air operations, and the ability to work in a cohesive unit."
