Notes: The Korean War. The American marines have their Communist enemies on the run until Chinese frogmen blow up a large bridge that the Americans are crossing while in pursuit. This leaves one marine batallion stranded on the enemy side of the river where they will soon have to face the much larger force of Communist soldiers. Then Captain Horn gets the idea to bring a bridge to the site. His men are sceptical but the men of the quartermaster airborne air supply and packaging company prove that it can be done thus saving the trapped battallion and forcing their enemies to go on the run again. - Joe Moore.
