Currently stuck on the LT-15 mission for the T-55A tank. Having a hard time accumulating 7k combined with having 4 tanks destroyed by teammates. Mostly I play the RU-251 and AMX 30 105. The RU is on like 57% wins while the AMX is lacking at 40%. So my question is how to improve as a light tank player and which other tank would help me achieve the mission easier.
