Old nameEdit
It was named "Assassin" in the post-game unlock screen for me, so I'm guessing it was a late name change. Alex T Snow 01:44, 13 November 2012 (EST)
Successor to CQBEdit
Vanguard is designed for Face to Face combat, its helmet also resembles a heavily modified CQB helmet. --SpartanS36 (talk) 23:53, 9 July 2013 (EDT)
