GI Joe (2013) #4 (Cover B)

HOMEFRONT! DOC has only precious minutes to save a teammate's life as the forces of COBRA close in-and her injuries prevent her from performing the operation herself. Is another G.I. JOE member ready for a crash course in battlefield surgery? Plus: Can ROADBLOCK & Co. convince the people of Warrenton to turn against COBRA? All this and the return of SCRAP IRON! WHO DOESN'T LOVE SCRAP IRON?!!?
