General Ernest von Helmreich is a secondary villain in The Rat Patrol, appearing in the episode The Wildest Raid of All. He was played by Wolfgang Preiss.
Von Helmreich was Captain Hans Dietrich's superior officer. He was one of the Afrika Korps' most famous generals, having been personally decorated by Hitler twice. He was kidnapped by the Rat Patrol to use as a bargaining chip allowing them entry into an Afrika Korps ammunition dump so they could destroy it. He was presumably killed when the ammunition dump exploded.
