M808B Scorpion

"This here is 66 tons of straight-up, HE-spewin', dee-vine intervention!"

- Avery J. Johnson

The M808B Main Battle Tank is a variant of the M808 Scorpion. The tank features a coaxial-mounted M247T machine gun.

Design
Essentially sporting the same design with the M808 Scorpion, the M808B differs from base model in such that its secondary armament has been moved from a pintle mount to a coaxial mount. The M247T machine gun is mounted beside the primary weapon and thus points in the same general direction as the main armament, relying in the turret's ability to traverse in order to change arc.

Changes
The M808B Scorpion Tank makes its first appearance in Halo: Combat Evolved, in the campaign level Assault on the Control Room; it is also available in the multiplayer levels Blood Gulch and Sidewinder. The tank is a dull gray, it moves at a decent speed, and it has a lightly protected canopy in multiplayer, although this is not so in Campaign. Because of this, it is easy for a sniper to kill the driver of the tank, effectively disabling it. Players also have the option of riding on the tank's tread covers in multiplayer.

Changes from Halo: Combat Evolved to Halo 2

 * The color of the tank has now changed from brownish gray to olive green, and the textures have also been updated.
 * Players now cannot ride on the tank's tread covers, called 'hotseats'. Standing on them is much easier with the revamped physics engine.
 * The reticule for the tank has also changed and is a lot smaller, for increased accuracy.
 * The tank now moves a lot slower, further limiting its movement and its evasive capabilities.
 * The tank's canopy has been replaced with a solid metal cover like in Halo: Combat Evolved's Campaign, preventing the driver from being sniped while it is intact. However, vehicle damage has been added to human vehicles, and so the player is in danger of the tank exploding if too much damage is taken.
 * The main cannon reloads twice as fast, requiring only a two second delay. The dots during the reload time are now removed. It is also more accurate.
 * The machine gun is now much more accurate. Previously, the machine gun fired in a very wide area.
 * Driving and aiming controls are now completely divorced allowing for greater maneuverability when firing. Previously the aiming and steering controls were linked, meaning the player had to steer more or less in the same direction they were aiming.

Variants

 * M808B2 Sun Devil: A modification with four 40mm autocannons.
 * M808B3 Tarantula: A variant with twin Scimitar 4x178mm rocket pods.

Halo: Combat Evolved

 * When you first acquire the tank on Assault on the Control Room, and clear out the Wraiths, the best way to take out the Banshee is to turn the tank around, look right up to the structure where it takes off from, and backup until you receive the checkpoint. Once the Banshee takes off, start moving forward and do not open fire until the Banshee has fired its Fuel Rod Cannon; after the round hits the ground, take aim and take it down.
 * Later on, after you move into the valley with the second set of Hunters, as soon as you get to the bottom of the slope, quickly turn around and head back up the ice ramp to take out the Covenant dropship attempting to flank you from behind. Be sure to watch out for your Marines, as they will also follow you up the slope.

Halo 2

 * Ditch the tank completely on "Delta Halo" when you proceed into the structures. Just use the Warthog, as your mistakes will be limited - especially when you must take on the Ghosts in the later part of the level.

Multiplayer

 * In Halo: Combat Evolved, even small pieces of cover, such as the spires on the top of Blood Gulch's bases, can stop players taking damage. Taking cover behind these spires while the cannon fires and firing while it reloads is effective, just watch out for the machine gun, which at close range, is quite lethal.
 * In Halo: Combat Evolved where the driver is exposed, it is possible to eliminate him with a single shot from a sniper rifle. However, if the player fails to kill the driver and is exposed, his tactic may turn against him and result in his death. Because of that, this tactic can be suicidal in some occasions. The pistol can also be used this way, but it requires more shots than a sniper rifle.
 * Although you cannot ride on the tread covers like you could in Halo: Combat Evolved, a player who has taken the enemy's flag can still ride the tank by jumping on the tread cover and staying put; they will not fall off as usual and can ride all the way back to the base with extra firepower supporting you.
 * Equipped with a powerful gun, the Scorpion can easily take out any aircraft it lays its eyes on. A way to counter this is to position your aircraft directly above the tank where its "blind spot" is. Then lower the aircraft on top of the tank keeping sure that you're still in its blind spot. Then, get out of the aircraft and jump on it and stick it with a grenade effectively destroying the tank. This tactic is primarily for use by the Hornet and Falcon with them being the only two vehicles with VTOL technology. This tactic can still be employed with the Banshee, but with a less effective outcome.

Trivia
In Halo: Combat Evolved, the Scorpion tank's cannon was a solid object, but in Halo 2 and Halo 3, the player will go through if they try to walk on the barrel - the character's legs will separate from their body. In Halo Anniversary Edition the M808B was actually just a M808 with the regular gunner seat destroyed and able to fire from where the M808B's machine gun was. Despite this there is actually nowhere for the machine gun fire to come out of and it just appears. The Wraith's secondary gun is also on it in this game though it cannot be interacted with and acts like it is not there.
