Im not sure but "it saw combat" is like "it shoot down 1 plane" or "it was shoot down by" not "he was close to another enemy plane" cuz thats not combat so the criteria don't match what is needed to add a plane.
+1
But sadly we can't have it. :/
Saw combat, as in fired its guns in anger and/or was fired upon in anger. The Meteor meets both of those qualifications. It doesn't matter if it was AA guns on the ground or aircraft in the air. I assure you, the Germans didn't just let it shoot things up without shooting back when it was doing ground attacks.
