bug or exploit?

I got pistol expertise from emptying a python into an attack helicopter...


p.s. ACOG on Python = win.

I think you may have gotten the challenge for emptying an entire clip into an enemy without missing, and you get reg for a chopper so thats my guess at least

I wonder if this works for all guns?

The only one I've gotten was the Sniper one. I was pretty proud when I got that.
