GRIZZLY TANK.
This tank is the most basic of youre vehicles but can still be very effective.
these tanks are cheep so you can make a large number of these without hurting youre bank balance.
The most effictiant way to use these tanks is in large numbers so if infantry oppose you just run them over its much quicker than to stand and fight.
The grizzly is great aganist all structures so if you use them to destroy the enemy base try to give them some form of support against enemy fire.
GOOD LUCK.
