Coordination and cooperation between the USAAF, the RAF, and Allied naval and ground forces were a major concern to British and American leaders at the Casablanca Conference.
One RAF tactic, the Tedder Carpet, consisted of successive squadrons of bombers dropping a rolling barrage of bombs, ahead of their advancing forces.
Another close air support tactic involved the highly mobile leap-frogging of interspersed landing fields to facilitate the performance of 1) attack; 2) top cover; and 3) reserve (refueling) fighter and fighter-bomber squadrons.
A major exception to this convention existed in the MAC headquarters itself, where Tedder's Deputy Commander-in-Chief was Air Vice Marshal H. E. P.
[citation needed] However, the MAC chief of staff was American Brigadier General Howard A. Craig, who had been schooled in desert warfare army-air operations by both Tedder and Field Marshal Bernard Montgomery.
