When I'm in a tank fight, I'm obviously gonna take a few hits, now I fight down to the red, but when I'm almost fragged, I like to haul ass in reverse and hopefully repair my tank to fight again. What ****es me off is that people always seem to be right behind me, pushing me right back in to be destroyed. This is not school kiddies, you don't need to form lines! I move for people who are in the red and trying to make it behind 'friendly' lines, so please return the favor. Also, don't follow behind the guy in front of you, try and stay beside them, so you don't block each others shots and movements.
I may be asking a lot, it doesn't seem so, but I may be. Just remember that your team is not just fodder for you to take advantage of.
