Robert Pirosh
During the war, Pirosh rose to the rank of Master Sergeant serving with the 320th Regiment, 35th Division. He saw action during both the Ardennes and Rhineland campaigns and was awarded the Bronze Star. During the Battle of the Bulge, Pirosh led a patrol into Bastogne to lend support to the beleaguered defenders. Profoundly affected by these experiences, Pirosh spent much of his later career paying tribute to the frontline infantry soldier.
Another piece fo triva. After filming for many hours, in the heavy metal helmets, Vic Morrow, the actor who plays Sgt Saunders, replaced the metal helmet with a fiberglass helment, with a camo cover. That is why is isn't wearing a period correct helmet.
