Yes, but just because they were assignd to combat units doesn't mean they actually did more than sit there without fuel.
Sorry. The list isn't proof.
It doesn't matter anyways. The Me262 was a significant and powerful fighter if 150 fought, or if 1500 fought. We already have it in AH so the numbers don't affect that either. It is perked due to how powerful it is, not its numbers, so once again, the actual number in combat does not matter.
