I find it depends who you are, and what you've done in your career.
There are guys that go as far as wearing unit citations, berets and salute each other on the field. I think that's going way too far.
And a group of my friends and I were confronted for all wearing camo pants in public.
There's nothing wrong with wearing camo, it's just camo.
I know a handful of really hardcore guys that are and were in the service, what I get from them is just don't wear anything that needs to be earned.
But a lot of people forget that airsoft isn't necessarily mil-sim, it's a sport, just like paintball. The majority of us aren't wannabe soldiers, we just wanna go out and shoot each other lol
