The Rat Patrol - Season 1 Episode 19
The Two for One Raid

Valuable German ammo has been dropped by parachute to an Arab farmhouse, and the Rat Patrol is sent to destroy it. On destroying the building, Troy discovers that there is no ammo--but there is a confused teenage boy. The boy proves out to be the son of a German commander. Troy is going to kill the commander, but when the boy pleads with him not to, Troy remembers what it felt like to lose his own father, who died when Troy was this boys age. Troy arranges to capture the German instead of killing him.
