WWII US Army Air Corps, 33rd Bomber leather squadron patch removed from the flight jacket. After the Pearl Harbor Attack, the squadron was transferred to the West Coast, flying anti-submarine patrols from Muroc AAF, California from December 1941 to the end of January 1942. It was then assigned to the new Fifth Air Force, originally based on the Philippines, leaving the B-18s at Muroc, being redesignated as the 408th Bombardment Squadron. By the time the squadron arrived in the theater the situation on the Philippines was desperate, and the squadron was based in Australia. From there it attacked Japanese targets on Papua New Guinea and New Britain. In October 1943 the B-26 Marauders were joined by B-25 Mitchells, and for the rest of the year the group continued to operate in support of Allied troops on New Guinea.This printed patch shows mild wear but overall is in excellent condition.
