Whenever I get a little too comfortable with the flying vehicles in Battlefield 3, someone either better than me or at a higher level manages to pull something off, leaving me to flip a table out of rage.
Not to toot my own horn, but I'm really good with the scout helicopters. I'd say one of the better people out there. It doesn't matter if you've got two buddies on each side repairing your helicopter, I can shoot it down (once you've gotten the hang of flying, the trick is to notice that the crosshair's in the scout helicopter's actually don't point to where it will shoot, it shoots a little bit under it). I just unlocked the air to ground missile in the heli, pretty much making unstoppable, provided I figure out how to dodge all the people who inevitably take out their stinger's.
I ended up getting the lock on indicator, so seeing how I had just shot down the other team's helicopter, I just decided to let it hit me and land on the ground to fix it.
Turns out the tanks can unlock Ground to Air missles. Which you can't block with flares. Which kill you in one hit. Which is practically unavoidable.
My team were being useless shits and instead of playing the game, they were all trolling the spawn waiting for a helicopter, so I ended up saying "fuck you guys, deal with it yourselves", and then I left.
