G.I. Joe, a Real American Hero #7

The cover of this January 1983 Marvel issue tells its own dramatic story in a single image: two soldiers — one in camouflage fatigues and a green beret, the other in a brown uniform and cap — stand back-to-back amid bursting gunfire and explosions, their weapons blazing outward at a surrounding force of blue-uniformed enemies. The tagline says it all: "A moment ago they were enemies… now they fight together against the greatest evil in the world!" Herb Trimpe's pencils and Chic Stone's inks give the scene a kinetic, hard-edged energy that makes this wartime alliance feel genuinely tense and earned.
