Mission was one of those fight over a single point ones, so of course everyone was focused on one point. The problem: this point was smack dab in an open field. There was cover in the point, but the problem was getting to it. Neither team could advance and anyone that tried got shot for their trouble. However: the point was far on the West side of the map. I took a weaker but faster tank, and drove around to the East. I managed a semi-circle, ending up right behind their front line, the main ones keeping my team bogged down: a group of tank destroyers. I like to imagine it from their perspective: sniping at some idiots trying to advance, keeping people off the point. They go out into third person view to get a better look around and see a cannon poking onto the screen, and their minimap doesn't show any allies next to them. Surprise, [expletive deleted].
Turns out, it doesn't matter that your tank is a full tier lower than their's if you get right up behind them before you fire a High Explosive Armor Piercing round right into their ammunition.
I took out three of them before they realized I was there, and a fourth for good measure before I got blown to bits by a heavy tank, but we had time to capture the point and from there, the stalemate just meant they couldn't get close enough to recapture it.
