The Joint Special Operations Command, or JSOC, was a component of the United States armed forces responsible for counter-terrorism training and operations among all branches of the military. Based at Fort Bragg, North Carolina, JSOC trained groups such as the Army's Delta Force, Navy SEAL Team Six, and elements the FBI's Hostage Rescue Team, among others.
- The following is based on the account of Operation Nightfall from Findings at CTU, which was later retconned in 24: Nightfall.
After Victor Drazen relocated to Đakovica in southwest Kosovo, JSOC feared he was planning to escape into the Albanian Alps and evade capture by NATO forces. Under orders from the Senate Special Defense Appropriations Committee, JSOC arranged a mission, codenamed Nightfall, to assassinate Drazen at his compound in Đakovica. Delta Force operator Jack Bauer was reactivated and briefed at Fort Bragg, where he assembled a six-man team and prepared for the mission. JSOC pre-programmed the team's radios with encrypted frequencies to avoid detection by Drazen's forces, but these codes were somehow leaked, resulting in the deaths of everyone on the team except Bauer.
