G.I. Joe, a Real American Hero #28

In "Swampfire!", the G.I. Joe team races into the Everglades to take down Zartan’s hideout, while the Baroness plots an assassination in Springfield—setting off a chain of high-stakes maneuvers across two fronts. With Destro and Firefly launching a new threat using the Rattler jets, the Joes fight back from the W.H.A.L.E. and Dragonfly, narrowly keeping the Commander one step ahead, as Zartan and the Dreadnoks vanish northward, leaving Firefly behind to clean up the aftermath. Written by Larry Hama and illustrated by Marie Severin, with inks by Andy Mushynsky, colors by George Roussos, and letters by Rick Parker, this 1984 Marvel issue features a cover by Mike Zeck and John Beatty.
