Thought, I should give an update. Thanks for all the help!

Who's getting offended?
Unless you're literally impersonating one with false valor (like people do to get discounts and free food) I don't know any soldiers or veterans who'd get offended. If anything, those who cared at all would be flattered.

I wasn’t going to impersonate a soldier, but apparently just dressing like a modern day soldier offends some soldiers.

I've never seen a single one get upset over it, especially if it's just for halloween. Even outside of that, they tend to have a thick skin with most things.

I've seen it offend non-soldiers, but never seen a soldier get upset unless the person was literally pretending to have served.

alright

Sit but you should have been a plane hitting a tower
