their bomber squadrons into a separate wholly RCAF formation within Bomber Command (No. 6 Group), commanded by a Canadian air vice-marshal. This was something the Australians and New Zealanders did not achieve. Several other RAAF and RCAF units, which were not covered by Article XV, were also under RAF operational control (see below). Initially, there was no cross-posting of personnel to or from these squadrons by the RAF and other Dominion air forces, although this requirement was relaxed later in the war. The remaining dominion, South Africa, was not a signatory to the BCATP and the South African Air Force (SAAF) did not form any Article XV squadrons. However, South Africa provided training facilities for some Article XV personnel, and many SAAF units took part in the East African, North African and Italian Campaigns. Furthermore, as the war progressed, personnel from other Dominion air forces were transferred to SAAF units and vice versa, in North Africa, the Mediterranean and Italy. Southern Rhodesia (later Zimbabwe) was not technically a Dominion and was therefore not a signatory to the BCATP, although aircrews from other dominions were trained there. In 1940, the small Southern Rhodesia Air Force was designated No. 237 (Rhodesia) Squadron RAF. Two other RAF squadrons, No. 44 (Rhodesia) Squadron RAF and No. 266 (Rhodesia) Squadron RAF were also formed; both had significant numbers of Rhodesian personnel. No. 75 (New Zealand) Squadron RAF had a status similar to the Rhodesian squadrons, and was not officially an Article XV squadron, although it was staffed primarily by RNZAF aircrew during the war and was officially transferred to the RNZAF in late 1945. While RAF units were not covered by Article XV, four British squadrons had a similar status: they were stationed in Australia, under RAAF operational control, for part of the war. These units were: No. 54 Squadron RAF, No. 548 Squadron RAF, No. 549 Squadron RAF and No. 618 Squadron RAF.
