El Sargento Furia y Sus Comandos #137

While attending the burial of US soldiers, the commandos vow to take revenge on the Japanese. During a submarine mission, they are captured by the Japanese who use underwater mines as a trap. As captives, the commandos meet a nun who offers to help them escape. When their plan goes sideways, the commandoes doubt the nun's allegiance. The nun uses her prior relationship with the Japanese soldiers to convince them that she is helping recapture them, but it's actually a double-cross to facilitate the commandos' escape. In the final twist, the nun reveals she's a beautiful blond spy, not a nun.
