1. On the Wetlands map, center base; we (MEC) had the surrounding bases and our armor was trying to come in from the west side. I made my way to the top of the hill as support and saw a squad trying to boobytrap the road coming in from the west. I just jumped the fence and layed down with my PKM and decimated the 3 guys. Then I went to the top of the house next to the flag, with the stairs on the side and see a USMC AT trying to take potshots over the back of the hill at my reinforcements, so I gunned him down. I crawled back to the front when I start hearing "Medic!" and "Clear! Recharding!" I move back to the rear and see a medic n00b trying to revive him and as he does, I lay them both out again. So, in summary; 6 kills on the PKM in 1 minute without reloading.
2. On Wake as PLA, start of the round, sitting in AA (pre-1.2) at landing beach; I'm watching an F-35 come across perpendicular to the road, I get a tone lock on him and fire the two missiles; he counters with his flares, deploying them as he crosses the land but that only attracts my missiles to the blackhawk just coming into South base; it was fully loaded - 6 kills :-). I've also had similar instances as the USMC where I've done the exact opposite and gotten a metric buttload of teamkills from a stray stinger.
3. Funniest Teamkill; I was playing USMC medic on Sharqi, defending flag on third story of construction site; I hear screams for "I need a Medic!" and see the indicator coming from the ground level, so I run to the edge, jump, and deploy the chute as I'm looking at the guy who needs the health. I landed smack on his head: DjnewellMIT[Teamkills]poorguy. Although, his problem was solved.
