G.I. Combat #28 (1955)

On a remote Pacific island, U.S. infantry troops prepare for a military test under the shadow of an impending atomic explosion, only to find themselves caught in a sudden, unexpected artillery barrage from an unknown source. As the smoke clears, they realize they’re not just facing the aftermath of a bomb test—they’re in the middle of a real battle, with enemy forces emerging from the island’s deserted zones, and no clear explanation for the sudden attack.

Two American G.I. border guards spot three fleeing scientists crossing the Iron Curtain under fire, rushing to bring them to safety just as a full-scale Soviet invasion begins. With their outpost overrun and reinforcements hours away, Colonel Mark Dillard must hold the line against tanks and infantry using only a handful of men, a mortar team, and sheer grit.

In the rugged terrain of northern Greece, NATO forces launch a daring assault on Red Mountain, a heavily fortified stronghold held by Communist guerrillas. As armored units push forward under relentless fire, the battle shifts to the infantry when tanks are forced to halt, leaving the troops to advance through deadly enemy positions and crumbling bunkers. With artillery paving a precarious path up the mountain, the men press on, determined to break through the enemy's defenses one bunker at a time.

On a remote island off the China coast, a downed American pilot narrowly escapes capture and signals for help, setting off a desperate rescue mission. As Marine forces launch a daring assault to free American hostages held by Communist forces, they’re stunned when the enemy uses the captives as human shields, forcing the Marines into a deadly tactical dilemma.
