My father-in-law was in the 1st Marine Division in Korea and he said they loved to see the Corsairs coming, they always clobbered the Chinese and Norks. He never mentioned what branch, but I assumed they would be Navy.
Navy or Marine. It was designed as a Navy aircraft, but early problems and squeamishness of navy brass relegated it to the Corps initially until they worked out carrier ops.
Navy and the Marines flew the Corsair. The Marines liked it better than the Navy, I believe. Was a bear to manage on/off the carrier.
My Dad was there and said you could pick up spent .50 cal cases from the Corsairs which were still uncomfortably warm to the touch.
