Continuity mistake: As the squad are taking a break on top of a hill, just before the fighter-bomber attacks them, Corporal Job is distributing ammo and Jonesey can be seen walking past in the background with four boxes of K-rations. A moment later, Crapgame and Jonesey are sitting together sharing the contents of the boxes. After Crapgame goes to the jeep for some water, the shot cuts to Kelly sitting by a tree. Jonesey walks up to Kelly with a message from Big Joe - carrying four unopened K-rations boxes.
Trivia: Actor Richard Davalos kept his bayonet razor sharp and accidentally stabbed Telly Savalas in the arm during the scene where the squad jumps over the wall to ambush the Germans on the road, warranting bandages on Savalas' arm. In the film, Savalas kept his shirt sleeves rolled up, until he was stabbed, and then kept his sleeves rolled down to hide the bandages.
Trivia: As Oddball's Sherman tank rolls through a town, an old man gets up to look around the corner to observe the tanks passing through. After that scene, the old man had a heart attack and died immediately after. Donald Sutherland and members of the film crew tried to save him, but were unsuccessful. The film crew built the old man's coffin for his burial and the cast and crew raised money for his family.
