Want to know what an enemy's squad is? kill em and look em up on the roster 
You've completely missed the concept of what I'm talking about. IRL, squads flew certain plane types with unique skins and ID markings. We can't do this in game because any squad can fly any plane with any skin (sometimes identical skins). I'm asking for the ability to be able to ID a player's squad affiliation as if I could recognize them in flight. (e.g. the 91st BG flies B-17's with a skin that has a large letter
A inside a triangle on the tail during squad missions. Now we don't fly that every sortie and plenty of other non-squad players use it, but with this system people around us could recognize us as the 91st as if we alone flew that specific setup every time.)
This would work for all planes/vehicles within a certain distance (say D800) regardless of being friend or foe. I'd like for it to be enabled for enemy cons as well because it gives an added dimension of, not to sound too serious,
knowing your enemy as you engage. I don't think this would immediately out a specific individual unless their flying alone, or would be detrimental enough to affect the outcome. For friendly missions, it would be easy for the coordinator and others to see who is familiar with one another to assign tasks. ("OK, those three guys are with the Claim Jumpers. I'm going to assign them to hit the town.") This could help build squad reputations and perceptions within the AH community.
