One on Wake Island, with my beloved M24. A jeep is racing towards me to run me over. I crouch, level the crosshairs on his head and pop him off. The jeep stops inches before my face.
The G3.
I am THRILLED that it is going to be improved because it is so damn beautiful already. Every time I use it I have at least one kill where I am like "haha.. that was bs... that guy is sure to be pissed off now". Things like, only having one round left and coming around the corner and smacking the round through an enemy's face. Or sniping people who are gunning for me from Humvees. People look at the 20 round clip and cringe, but seriously, that is 4 - 6 kills if you know how to use it. I never die because of the 20 round clip, though I often run out of magazines and end up with pistol. The G3 is my charm. Battle Rifle > Assault Rifle
One time, I shot a guy with the G36C and fell back to reload. Meanwhile I hear his teammate revive him, so I pop out to kill them both, but the teammate has left, so I kill him again. Then the teammate revives again. This happens 2 or 3 more times, then I am like "hell with this!" and throw a grenade around the corner.
