Hmmmm well I got the "The One Free Bullet", "Neighborhood Watch" "and "Little Rocket Man" achievements, little rocket man was by far the harder of the three (hard to image right, but trying to run half a mile in open ground, punting and trying to refind a gnome while a combine helicopter is shooting at you is hard as all hell).
In Battlfield Bad Company I shot down a helicopter with my main tank gun at least one time, shot down two(I think it was two) helicopters using the tank mounted machine gun, shot down around two helicopters with direct man-fired rocket fire(no tracer assistance). Shot down more with assult rifle fire, and I think I once killed a pilot with a sniper round causing his helicopter to crash(Can't remember if this occured in Bad company or another battlefeld game).
Also once knifed over five guys in a row in Battlefield Bad Company, came up behind them all as they were sniping on the hillside while I was playing defender on that farm map.
And my epic Battlefield Bad Company story of awsomeness:
Once in battlefield bad company I got in this great 4 man squad (I served as a kinda dual squad and tank commander) while doing goldrush on the desert oasis map, working together we went with 2 heavy abram tanks. We worked together to drive past the enemy armor, snipers (the most deadly thing for a tank in that game, so fucking overpowered), enemy weapon emplacements, and infantry to the second line of defense. We then preceeded to park our tanks in the poppy fields behind the main bulding alongside each other in a horizontal manner, and fire tank rounds and tank-mounted machinegun rounds into the back of the buildings, killing dozens of enemy players. Having failed to kill us with armor or rockets from the building and rear walls (we killed them before they could get off more than one or two shots at most) and using our support members to heal the tanks from safety as they stood behind the tank at all times. The enemy became so desparate to stop us, many of them went as either demolitions or spec ops and tried to charge through the couple yards of feet keeping us apart. We mowed them down by the dozens with our tank-mounted machineguns and small weapons fire. We had at least half the enemy team focusing soley on us, since we could hit them from where they camped or spawned. After several gruelling minutes of mowing them down without any losses, the tanks started to get damaged too quickly for the support guys to keep up, and the enemy kept charging the field trying to get close enough to plant C4 charges. Having overheated my tanks weapons once again, and seeing enemy's within only a few yards of our support classes, and my tank life low, I bailed outta my tank with my M16 and preceeded to mow them down with that. Since the enemy were now too close to us, I couldn't spare enough time to reenter my tank. Still I fought on, taking down several enemies without direct assistance from my team, who were too busy trying to save the other tank (my tank was destroyed while unoccupied). After a minute of this I finally took a shot that killed me. My team fought on without me but was overwhelmed without the extra support of the second tank or myself(not that I could have held them off much longer like I was). In all I got over 40 kills (not counting assists) with less than 4 deaths total. My squad killed well over 100 enemy's total, also with each man suffering very few deaths. We had held off the majority of the enemy team, inflicted very heavy losses on them, and destroyed tons of their vehicles and defensive buildings, cover, and weapon emplacements. All for over 10 minutes without any outside support from the rest of the our team. I am proud to have been a member of that squad, and to be able to tell this gaming tale.
PS: And on a lighter note Ive decked out my own sides tanks and artillery in flashing tracer rounds so they look like Christmas trees.
