There is no salute function in Call of Duty. The ends justify the means crowd and win at all costs people can't handle a good fight if they lose, and if they do send a salute it's facetious at best, mocking you after they ho'd you for the "win" most likely.
I wouldn't sweat it, Tom. You'll contine to fly and act with class, let it be an example maybe a few people will pick up on and realize it's the better way to play.
