The Brave And The Bold #162 1980

In "Operation: Time Bomb," Batman joins forces with Sgt. Rock and Easy Company during World War II to thwart the nefarious Iron Major's plan to detonate a time bomb against the Allied Forces. Batman infiltrates the enemy's stronghold but is captured, leading to a daring rescue by Sgt. Rock and his men. The ensuing battle culminates in the destruction of the Nazi castle, leaving the Iron Major's fate uncertain. This issue is notable for its classic Batman team-up with the legendary Sgt. Rock, featuring art by Jim Aparo.
