In this battle. First I try to be a long range sniper. And I destroy an enemy's tank. But you can see. in this way it's hard to find enemy.

And then I use the advantage of Terrain. is more easy kill enemy. but in these battle. all tank can move fast. so i guess maybe the good way is keep move. not just move forward.

Atleast! we destroy three enemy's tank. This time. It's Getting better to control these tanks.
