I like to steal tanks from the enemy, or even better, like this:2 Mammoths on under. I drive behind them in my stealth tank. Since both were damaged by 2 Nod Flame Tanks, one engi gets out to repair. I drive over him with my stealth tank, and the mammoth just sits there, the other not noticing. One of our black hands (stealth ofcourse) jumped in and together we killed the other mammoth. Then we rushed the AGT with the mammoth, my stealth, 2 other stealths that joined us and a light tank. We won quickly after that.
