MIRAGE TANK. I really like these units they are very good against infantry can kill with just one shot. As you may have noticed these tanks can camouflage themselves when there not on the move. The only camouflage they have is a tree but place these tanks in the middle of a forrest they will not be found for some time but you would have already killed alot of the enemy units before you may be discovered. The forrset trick is very good but if you just think about it you could simply make youre own forrest of just mirage tanks. Build atleast 5 and put them together in a group now when youre enemy see's then trees he will think nothing of it and misstake it for a small forrest. GOOD LUCK.
