I'm pretty sure there was at least one squadron based in Europe at the end of the war and flew combat missions. I remember someone posting about it in here a long time ago with a link to the squadrons operational history.
616 Squadron flying Meteor IIIs, they were part of the 2nd TAF.
It is interesting to note that the Meteor I entered service in mid 1944, about the same time as the Tempest and P-51D but was kept back in Britain to protect against the V-1. Had the Luftwaffe been more active during this time then undoubtedly it would have seen action. The IIIs on the continent destroyed aircraft on the ground, but never managed air to air combat because the Luftwaffe was a no show.
I think the Meteor more than qualifies to be in AH, it was part of the Allied inventory for a long time during the war and had the Luftwaffe been more active during this time then it would have seen a lot of combat. All the Germans had to do was take off and immediately they would be in air to air combat, i guess to some this makes their aircraft more valid. The 163 is in game, and that only saw service in JG400 as far as i know. I believe that the Meteor probably destroyed more enemy aircraft that the Komet did, just the Meteor got them on the ground and the 163 got them in the air, plus all the V-1 kills.
