Pick Up Trucks - These basic civilian trucks have room for two, no armor, and no weapons. They are fast and maneuverable, so you may occasionally want to use one, but get hit in one of these and you’re dead.
LTVs - You’ll see a lot of these four-wheel drive beasts zooming around and they look like Humvees. They seat five and have a roof-mounted gun. They’re fast but only lightly armoured, and they won’t offer much protection if you get fired on, especially if the attacker aims for the windows. Offensively speaking, the roof-mounted gun is prone to overheating if you fire continuously for too long. In easy or normal difficulty, it can be fired by the driver. Otherwise it requires a dedicated gunner.
Troop Transports - These are much bigger trucks, they are covered, are more heavily armored, and they feature a roof mounted gun just like the LTV. These can carry loads of troops, but they are slow and cumbersome to drive.
Attacking Trucks - All of the trucks are easy to destroy, and they don’t offer much protection for the troops inside. You can shoot them through the windows, use explosives to turn them, or you can shoot out the individual tires to stop them in their tracks.
US and Korean Tanks - Sadly you don’t get to engage in much tank action. There are a couple of different types of Korean tanks and an American tank. The standard US and Korean tanks are armed with cannons and machine guns, and they are faster and more maneuverable than you might expect. There is also a second type of Korean tank which can fire explosive rounds and rockets at a faster rate, but it lacks the machine gun.
