I'm Concept 1B Thunderbird. A fictional tier 10 heavy American tank. I have a 120mm gun with 380 damage, 7,6 seconds reload, my turret is incredibly durable because it is very thin and hard to hit, also I have great gun depression and decent accuracy. I'm also quite fast for a heavy tank.

Oh and also I've got an emergency track mechanic, that allows me to go backwards at speed of 7 km/h even if my main track is destroyed
