Synopsis:
Sgt. Rock and Easy Company are pinned down in a burned out building and surrounded by enemy troops. While waiting for the soldiers to move in on them, Sgt. Rock tries to calm the nerves of a new recruit named Smitty. He tells him the stories of Ice Cream Soldier and Bulldozer. While this is going on, the enemy soldiers make attempts to approach, but they are driven back. Finally, Sgt. Rock leads a charge out of the building and passed the enemy troops. Smitty, the new recruit, proved himself during the escape.
