The Seabees on Iwo Jima.

Narrated by CBS Sports' Jim Nantz. The Seabees on Iwo Jima focuses on the United States Naval Construction Battalions in World War II, which built all the infrastructure for the Allies in Europe and the Pacific in WWII. The Seabees were construction workers by trade but had to fight at times. Their motto was "We Build, We Fight," and their biggest test came in the battle for Iwo Jima in 1945.
