I got 5. Missed the M14 vs M1a. That was a trick question. I get the military vs civilian version, but I don't think you need a select fire for an honor guard....OK, maybe I took it too seriously
Got 6. I missed the mk46 mod 0. Didn't know we had that thing, it looked like any other m249 (fn minime) in that pic. The Russian sniper rifles really screwed me up, though.
