she's a sniper or not?

I thought this was a male hyena before I scrolled down below the shoulders, oops x3

Anyway I notice this as kind of a common pose for you. I'd think that since she's rather thin, about the waist especially, we would be able to see some of her right arm. For us to see none of it, it seems like she would have to be intentionally hiding it. Then again, you're the artist so her arm is wherever you say it is, heh. Doesn't really matter.

Very hot, and very militia-ey I especially like her tits. and the rifle, is that a M21?
