Tailgate was part of a bomb disposal unit with the Primal Vanguard. Hangers On
The Vanguard had its best days under the command of the legendary Delta Magnus. During the Interregnum, after Nova Prime went missing, the Guardians looked after the Matrix of Leadership until a new Prime could be found.
By the time of the Clampdown, the Vanguard had gone downhill. The organisation was mired in the "Phobos Controversy" and at one point an ex-Vanguard member was responsible for a shooting in Apophenia. Shadowplay, Part 1: Post Hoc Ironfist, however, continued to study and fangasm about the Delta Magnus days, filling his workspace with Vanguard artifacts and writing monographs about them.
