The Desert Air Force needed to be mobile

Since the Army was expected to be able to quickly advance against the German and Italian forces, the Desert Air Force needed to be prepared to advance with them, to be in a position to support the Army. The mobility would be required at both the wing and squadron levels. The plan was to leap frog the two wing headquarters units and their control centers. Finally, duplicate control centers were assembled for each wing, in order to be sufficiently mobile. Sufficient transport needed to be available, if mobility were to be a real possibility. In the end, there was just barely enough transport, but the lack of suitable vehicles "was felt throughout Crusader". This is based on the account in Vol.III of the Official History.
