Wright rapidly ascended to a position of prominence within the UVF ranks, eventually assuming leadership of the local Portadown unit. He became commander of the UVF's Mid-Ulster Brigade in the early 1990s, having taken over from his mentor Robin "the Jackal" Jackson, who had been the leader since July 1975 and one of Wright's instructors in the use of weaponry. Jackson was implicated in the 1974 Dublin car bombings, the Miami Showband killings, and a series of sectarian attacks. Founded in 1972 by its first commander Billy Hanna, the Mid-Ulster Brigade operated mainly around the Portadown and Lurgan areas. It was a self-contained, semi-autonomous unit which maintained a considerable distance from the Brigade Staff in Belfast. Holding the rank of brigadier, Wright directed up to 20 sectarian killings, according to the Northern Ireland security forces, although he was never convicted in connection with any of them.
