created a demand for training and recruitment films which proved difficult for Warner Bros. to fulfill. Jack Warner began the process of developing the organizational structure for an independent motion picture unit. The dual mission of the unit was to produce training and morale films, and to train combat cameramen. The ranks were to be filled with film industry professionals, the first time in history such a unit would be raised. On 1 July 1942, the First Motion Picture Unit became an active unit of the USAAF.

The 18th AAF Base Unit was unique in comparison to other military units in the methods employed to obtain recruits. Many members were well into middle age and unsuitable for combat duty.
