Lieutenant "Duke" Callahan, Yankee, was new to the desert war. He was tough -- but green. Lieutenant Bruce Wilson, Britisher, had been fighting sun, sand and Germans for a long time. He had plenty of toughness too -- but he knew how to use it. These two would have made a great team together. That was the idea. But they took to hating each other's guts -- and when that happened that big desert just wasn't big enough.
