Gents, here is what Corsairs where used for and by whom:
The U.S. Navy did not get into combat with the type until September 1943 and the Royal Navy’s FAA would qualify the type for carrier operations first. The U.S. Navy finally accepted the F4U for shipboard operations in April 1944, after the longer oleo strut was fitted, which finally eliminated the tendency to bounce.[39] The first Corsair unit to be based effectively on a carrier was the pioneer USMC squadron, VMF-124, which joined Essex. They were accompanied by VMF-213. The increasing need for fighter protection against kamikaze attacks resulted in more Corsair units being moved to carriers.[40] Despite the decision to issue the F4U to Marine Corps units, two Navy units, VF-12 (October 1942) and later VF-17 (April 1943) were equipped with the F4U. By April 1943, VF-12 had successfully completed deck landing qualification.[36] However, VF-12 soon abandoned its aircraft to the Marines. VF-17 kept its Corsairs, but was removed from its carrier, USS Bunker Hill, due to perceived difficulties in supplying parts at sea.[37] In November 1943, while operating as a shore-based unit in the Solomon Islands, VF-17 reinstalled the tail hooks so its F4Us could land and refuel while providing top cover over the task force participating in the carrier raid on Rabaul. The squadron’s pilots landed, refueled, and took off from their former home, Bunker Hill and the USS Essex on 11 November 1943.[38]
So you can use the them for Marines, USN and Royal Navy Fleet Air Arm. If you want to paint them USMC were a dark sea blue with MARINES on the fuselage, US Navy Corsairs same color just said NAVY on the side. RN light Blue with RN roundel. So Coach’s bad color Marines wont go to waste. Buy them and paint them up.
