Redshire, Encounter(I think, the one where both teams are going after a single cap point.) I'm in my T-50.
I rush to the point along with another t-50. No enemies yet despite some fast tanks on their side. No arty. I find a nice bush behind the point and hide. I watch a bunch of enemy lights move into the cover on the point and start capping. I sit there, content to spot for the moment and I watch as my heavy teammates lay waste to a cocksure Centurion and lay down fire at the visible tanks. A cheeky little Leopard has found cover and a nice bush. He's only infrequently visible to me from my spotting position, but I know exactly where he is. He's the one building up most of the cap points. 30, 40, 50. Other tanks continue to fight it out, but nobody on my team is moving on the point. 60,70. I load up HE ammo. 80. Leopard thinks he's got this one won. Nobody can hit him where he's sitting. Another tank moves into cover beside the leopard to speed it up. 90, 91, 92. I decide it's about time to reveal myself, even though I liked that spot and would have preferred to just spot for the rest of the game. I put 2 HE rounds into the leopard and 2 more into the other light tank, completely killing their nearly won capture bar. I high tail it out of there with only glancing blows. Teammates finally show up, just a few seconds too late and while they're scrubbing out the rubbish from the point, I run around, swing around once more and put the final shot into that leopard, just to add salt to the wound. From then on, the rest of my team just cleans up easily, while I sit on the point. Cap occurs just a few seconds after the last enemy was defeated.

Never let it be said that light tanks or HE rounds or the lowest tier tank are useless. They just need to be in the right place at the right time and it helps to have a whole lot of camo.
