M808C Scorpion/Gameplay

Campaign

 * Unless there is a large amount of infantry who can inflict large damage to you, let your gunner eliminate them. Vehicles, if present, are always your first priority.
 * You should always try to give your allies good weapons, such as the M41 Rocket Launcher. A good configuration, especially in tight quarters, such as those offered by Kizingo Boulevard, is to give the rear-most Marines Rocket Launchers, so they can destroy vehicles, and the other two Marines either the MA5C Assault Rifle or the M90 Shotgun, if possible, so they can kill any enemies which get close to the hull.
 * On higher difficulty levels, the Scorpion is highly vulnerable to being EMP'd by a Plasma Pistol. Any sign of anything charging a charged Plasma Pistol shot should be eliminated as soon as possible.

Multiplayer

 * Another popular tactic is to use a "hull-down" position. The tactic essentially requires the tank to be positioned such that its hull (the main part of the vehicle) is behind a crest or other raised ground, but its turret (or a superstructure or roof-mounted weapon) is exposed.
 * Using a Power Drain or a Plasma Pistol Overcharge will temporarily disable the tank's mobility and will greatly weaken its driver. While the tank's weaponry will still be functional, it will be unable to move and can be easily boarded.
 * An effective hijacking technique is to grab Active Camouflage and wait for the tank to pass-by or approach the player.
 * On Sandtrap, a good tactic to hijack a Scorpion is to wait for the tank to go into the middle depression and board it from above.
