If you are concerned about legality of something, opinions of photographers really doesn't matter.... If you are concerned enough to even post this, I would suggest getting it writing from someone with actual knowledge and authority. I would also be concerned something like military uniforms, people sometimes have strong opinions and so as nude body. It can start a firestorm even if it perfectly legal. All it takes is someone to start a blog post or something and get enough people upset over it. Next thing you know, you may be a target of all kind of threats. Just my personal opinion of course....
