Question from a photographer

Had a question I wanted to pose to you folks.

I have a contract that would have me taking photos of soldiers of different levels during training exercises for unit use. The last person I was told couldn't get his crap together and kept missing shots because he was fumbling with his gear and talking too much.

To not have to fumble with gear I had an idea of using a plate carrier and basically setting up a camera bag that I wear. This would put all of my gear "at the ready" but would bring a possible problem. The LAST thing I want to do is look like some kind of "wannabe." My goal is practicality. I know I'm bound to catch crap just because I'm the civilian.

So my question would be - If you were doing some sort of training, saw a photographer will all of his gear setup on a plate carrier - Is that something that might bring negative attention?

Thank you for any guidance you guys can provide.
