The Rat Patrol - Season 1 - Eps 21: The B Negative Raid
Moffitt is seriously wounded in a raid on a German convoy. The Patrol is far from help and so Troy decides to obtain blood from a nearby German field camp. Dietrich is in charge of the base; Troy encounters him and orders him to help him find a donor. Dietrich sends for Corporal Pennell (guest appearance by teen idol Fabian Forte), a captured Yank deserter. Pennell refuses to cooperate but Troy takes him at gunpoint. On the way back to Moffitt, Dietrich catches up to them and it is up to Pennell to do the "impossible" to prevent them from all being recaptured. He rises to the occasion and they make it back to Moffitt and Tully in time to save Moffitt's life.
