Valuable German ammunition has been dropped by parachute to an Arab farmhouse for a convoy to pick up, and the Rat Patrol must destroy it. On destroying the building, Troy discovers that there is no ammo--but there is a confused 16-year-old boy. The boy proves out to be the son of the German convoy commander. Even while the Rat's prisoner, the youth desperately tries to get word to the convoy so his father won't be killed. 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 boy's age. Troy captures the German instead of killing him. Then, the Rat Patrol destroys the convoy with the ammo. 

Moffitt gets seriously wounded during a raid on a German convoy with the Rat Patrol far behind enemy lines. 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, a captured American deserter. Pennell refuses to cooperate, but Troy takes him at gunpoint. On the way back to Moffitt, Dietrich catches up to them, and Pennell must 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. As for Pennell's future, Troy will say the corporal was, unfortunately, separated from his unit by accident.
