War is here and we can't do anything about that. Even if, we don't like, we need to go into war to fight for our country. You are a sergeant and you got a vehicle of your own. Use the vehicle to fight for your country.
Drive your truck in the battlefield. Like most truck games, you shouldn't bump the other trucks since it will damage your truck too. Try to maneuver your truck all around the enemies and keep firing. Some of the fallen enemies will drop a cargo that can help you in the battlefield.
