The Gun Runner Raid - S1.E12

An Arab convoy, disguised as Americans, traps and captures the Rat Patrol. The convoy's leader is Ned Cunningham, an ex-Yank hero turned gunrunner. He sells now to the highest bidder, no matter which side. He feels that the Rat Patrol is costing him too much business and so is going to eliminate them. But he then decides he likes the Patrol and will take them into the deal if they will cooperate. In the end, though, his duplicitious behavior causes his own death.
