This gives me an idea for a bro vet T shirt: kind of a mashup of the knight crusader/dude in chain mail armor carrying sword and shield motif but also wearing a flight helmet. Helmet image comes in a choice of helo helmet or jet helmet styles but there's an upcharge for putting your squadron crest on the shield, all knights carry a shield... duh (or no charge for just a generic shield, which FYI might get you clobbered in battle when your friends don't recognize you).
