i think the defenition of seeing combat means seeing combat against the enemy or in a combat zone, it dosnt have to mean seeing combat against other aircraft to mean seeing combat. the meteor qualifies as seing combat as it was used against the enemy in a combat zone. ground attack or dogfighting or just being in a zone of conflict or combat counts as seeing combat.
an example. my grandfather served in vietnan as a aviation mechanic, he worked on the F4 Phantom, and was never in a firefight against viet-cong or NVA troops, but still was awarded the combat action ribbon. i know its not a good example.
