Sgt. Slaughter
Sgt. Slaughter is not listed on the official listing of personnel in the Battle Files mini-series, which lists all active and reservist members. However, Sgt. Slaughter is listed as an active member of the G.I. Joe team in "G.I. Joe: America's Elite" #28. He is later seen working with Joe veteran 'Jane' to evacuate endangered Joe support personnel. In volume 2 of "G.I. Joe A Real American Hero", Sgt. Slaughter appears in a flashback as a drill sergeant for incoming Joe trainees, AKA Greenshirts. He works closely with Beach-Head.
