How do you beat autumn war mission 7

Buy Vehicles for the other units (for all the guys with M-4s) buy the APC that are described as fast on plains and road/the one you see in the title screen then click the gray turret. For the RPG troops buy the same vehicle but change to the artillery piece. Once you've the done this MOVE the guys with the tank {the icon that the unit has a vehicle is in the shape of an arrow}
pull everyone else back then put the tank unit in the woods when those zombies come within range {when the green arrow has a target on it} press the space-bar then click on the enemy.

First press the [FIRE] button
Then PRESS the Fall back button
Then watch the zombies fall from tank shots and bullets

keep doing this until you see the icon that looks like Triangle with legs on it coming in behind your tank bring those guys forward and kill every thing on sight
