This picture was taken in the Phillipines 1945, at an airfield captured by the Americans. Notice the Japanese wreckage tail section with Iron cross. Anyone ever heard of the Japanese using that on their insignia or have any idea what Japanese unit this might have been?
No, this is called in heraldry a cross pattée. Other names for it are cross pattee, crosse pattée, cross patty, cross formée, cross formy. In German it is called Tatzenkreuz.
