 A primary function of the FMPU was the training of combat cameramen . The units were based at nearby Page Military Academy . There were approximately 16 combat units , each made up of seven officers and between 20 and 30 enlisted men . They were trained to use a variety of photographic equipment and cameras and also received combat and weapons training . The cameramen were sent to every army air force base to document all aspects of the base 's operations as well as aerial battle tactics and enemy airplane performance . Every cameraman was trained to load film into their camera under adverse conditions , and if need be , to develop it on location . Most of the aerial motion picture photography shot during World War II was filmed by Fort Roach alumni .
