Last episode directed by Robert Altman.
Allegedly Director Robert Altman was fired because "Survival" was too Disturbing (NY Times). He directed 10 episodes in Season 1. As a kid we watched Combat! for kicks. Went out and recreated the episodes next day. This one was probably too dark for us 8 yr old kids.
It is revealed that Saunders has a brother named Joey.
During one of the times that Saunders is hallucinating, he gives his name, rank, and service number to an imaginary German interrogator. His service number is 2270622.
