My secondary weapon is almost always a stinger launcher. I shoot down every helicopter and flying object that I can.

I don't have nuke unlocked because I don't think I'll ever achieve a 25 kill streak. My record is 22.

ACR is my favorite weapon. It's very accurate but only useful with stopping power as it kills in 2 or 3 shots. I tried using it without stopping power and couldn't score a single kill.
