A heavily guarded German fortress appears impervious to the Rat Patrol's efforts to destroy its big supply depot. So, Troy determines their only chance to blow the depot is to capture a German tank and use it to get past the guards.

Capt. Richter must convey a large cache of "confiscated" diamonds to Berlin to finance the Nazi desert campaign. The Rat Patrol must steal the diamonds from a military HQ in the desert. But, brute force will not succeed, so they need to attempt a plan full of guile and cunning to pull the theft off. So, Troy infiltrates the German H.Q., posing as a blinded Afrika Korps officer.
