Following the dissolution of the O.S.S. in October of 1945, President Truman replaced it with the C.I.A. in 1946. In 1951, seeking to fill the void left by the retired JSA, Truman created Task Force X. Its domestic branch, Argent, was led by Control and consisted mainly of former O.S.S. agents, while the international branch, the Suicide Squad, was put under the command of General Jeb Stuart. Argent was a powerful agency during most of the Cold War. After confronting and killing a government official responsible for the assassination of President Kennedy, Control ordered all records of Argent destroyed and pulled the organisation undercover. For years, the Argent continued their work in secret, but shrunk considerably in size. Eventually, Control died, but his granddaughter, Anne-Marie Vere, maintained the pretence that he was still alive to keep the group operating. In recent times, a confrontation with the Suicide Squad exposed the deception and an embattled Argent disbanded. At the end, only six members were active.
Known agents of the Argent included: Control, Falcon, Fleur, "Iron" Munro, Phantom Lady I, and Anne-Marie Vere.
