Navy KIA sticker symbol or insignia?

Answer 1

On a US Navy warship it's the enemy's flag with a corresponding drawing of what was destroyed: During WW2; An enemy flag with a small airplane it they shot down a plane, or small warship painted along side the flag if they sank a warship. On a US Aircraft, during WW2 an enemy flag, sometimes with the written designation of what was shot down: During the Vietnam War; a RED STAR with MIG-21 written next to the star. Even though the North Vietnamese Air Force MIG's had YELLOW stars on their wings, for US pilots, all communists were RED's, therefore all communist aircraft shot down in Vietnam were designated by RED Stars. The US Air Force and the US Navy each have preserved in museums an F-4 Phantom II with 5 Red Stars painted on each one from the Vietnam War; the last US Ace's of the 20th Century.
