No. 10 OG's name was changed to First Tactical Air Force (No. 1 TAF) on 25 October 1944, ostensibly to emphasise "the formation's impressive size and ambitious purpose". Its complement of units was much greater than that typically assigned to RAAF groups, which were themselves considerably larger than USAAF "groups" that consisted of three or four squadrons. As the conflict gradually shifted further north, however, No. 1 TAF was relegated—in the absence of a Japanese air presence—to patrol, reconnaissance and some ground attack duties, including the Philippines campaign in 1944 and the Borneo campaign in 1945. By early 1945, there was widespread dissatisfaction among the fighter squadrons of No. 1 TAF due to its new focus on close air support duties. The underlying cause was the reluctance of the Allied Supreme Commander in the SWPA, Douglas MacArthur, to use non-American forces for the main advance towards Japan.
