My best was a 106 on Wake for a good long while, It's still my best actually PLAYING, not commanding.
I was US, as I recall. Started out defending one edge of the island as AT after it was capped. Basically, hanging around blasting anyone who came near with my shotgun, and popping transports with the rocket.
After a while, a pair of guys came along in a hummer, bailed as I rocketed it, and capped the Beach flag. I rushed to the rescue of the poor flag, finding one in the bunker. I approached, he bunnyhopped like mad. I emptied my shotgun into him, reloaded, and emptied it again. Dead. I step outside, his friend is running away. Can't catch him, so I pull out the pistol and drop him. Bam bam bam bam bam bam bam bam bam dead. This seems to piss them off immensely, as they keep coming back and getting killed. Every so often they kill me, but I come back and nail them after a respawn. Sometimes from the opposite end of the island, capping flags and killing people en route.
The battle continues on during this, and eventually the enemy is pinned down at the airfield. We close in, and repeated attempts to cap it fail, so we just lurk and frag anyone coming in. I ended up sat at the corner of the base with my rocket, whacking the J10 and the chopper as they tried to take off. Multiple kills from that, eventually end up crying for supplies.
After a while, the round ends. 106 score. Mostly from kills and flag caps. WTF, I think, that can't be right. I check again, and there I am, high in the rankings.
Otherwise, it's commanding on Karkand. Sitting there at the back of one of the MEC bases, directing the battle, and occasionally being fragged by someone passing and hearing me yelling orders.
