Avoiding detection
When searching and engaging enemy tanks, try to assume a hull-down position behind the crest of a hill. This will hide the lower portion of your tank, and minimize the risk of drawing enemy fire.
Easy kills
Press [F5] for Tc station view. Click the target lock and your target will become locked. Immediately press [Fire]. If the enemy tank tries to turn on smoke, the message "lost target" will happen. If so, immediately press [F4] then press [Fire].
