This article is about the iteration of the Scorpion tank introduced in Halo 5: Guardians. For other uses, see Scorpion (disambiguation).

The M820 Main Battle Tank, commonly known as the Scorpion, is the United Nations Space Command's primary main battle tank, introduced in 2557. Manufactured by Chalybs Defense Solutions,^[1] the M820 Scorpion is the successor of the M808 model used throughout the Human-Covenant War.^[2]

Specifications

Design details

The M820 Main Battle Tank is similar in most respects to its predecessor, the M808 MBT - it is a lightly built, highly mobile weapons platform, utilising four independently operating tracked bogies for high manoeuvrability on rugged terrain, and features a low hull profile with a highly placed cannon, with a cuppola pintle-mounted crew-serviced GPMG and room on the bogies for limited troop transport. It differs from the M808 in a number of important ways, however - it is significantly lighter than its 66 ton predecessor, at only 35 tons, and can achieve a top speed of 128.7 kilometers per hour (80 miles per hour), a significant improvement over the M808's top speed of 96.5 kmph (60 mph). However, it does not exchange mass for armor protection, retaining its survivability. The 90mm M512 smooth-bore high-velocity cannon has been replaced with a more powerful M990 electrothermal-chemical (ETC) 150mm smoothbore cannon, trading commonality of ammunition with older Scorpions for a new calibre that can accomodate future planned guided munitions and advances in energetic propellants. More importantly, the new Scorpion is built from the ground up with new technologies and techniques, lacking the Scorpion's deferred technology revisions and historical compromises.^[1]

Armaments

The Scorpion is outfitted with a 150mm M990 electrothermal-chemical smoothbore cannon, breaking legacy ammo compatibility with its M808 predecessor. Instead, the M820 Scorpion's cannon accommodates both planned cannon-launched guided munitions and future advances in energetic propellants.^[1] The Office of Naval Intelligence variant uses an experimental ammunition, and a variant of the Scorpion currently in skunkworks development by Hannibal Weapon Systems is set to incorporate directed-energy weapons, a laser-firing primary cannon and a Gauss repeater turret.^[3] The mainline M820 Scorpion is also armed with a pintle-mounted machine gun.^[1]

Variants

Corp Scorpion: An up-armored variant used by Liang Dortmund security forces to defend remote installations.^[4]
Tundra Scorpion: A Scorpion variant featuring tundra camouflage and better armor than the Corp variant.^[4]
Urban Scorpion: A Scorpion variant featuring urban camouflage and better armor than the Corp variant. Used by UNSC Army and UNSC Marine Corps units for deployment against Insurrectionists in urban areas.^[4]
Woodland Scorpion: A Scorpion variant featuring improved off-road maneuverability, simplifies air transport into remote areas and has better armor than the Corp variant.^[4]
ONI Scorpion: The ONI "security" Scorpion features heavier armor than the Urban variant and has an upgraded cannon utilizing experimental ammunition.^[4]
Hannibal Scorpion: Upgraded by Hannibal Weapon Systems, this variant is one of the corporation's several test bed tanks, outfitted with heavy armor and a directed-energy weapon.^[3]

Operational history

Though the M808 continued to serve in UNSC Army and Marine Corps armored units after 2557, the M820 Scorpion began to replace older materiel after its introduction.^[1] By 2558, the M820 had replaced its predecessor in War Games simulations aboard UNSC Infinity among its Spartan forces.^[4] Chalybs offered an a number of variants to buyers - UNSC armored units operated the baseline Scorpion, as well as Tundra, Urban and Woodland variants with camouflage paint schemes and improved armor, while ONI operated its own Scorpion variant for its Security forces which featured superior armor and used experimental rounds to improve lethality. Chalybs also offered a civilian variant of the Scorpion for private military contractors, the Corp Scorpion, which featured superior armor to the baseline Scorpion. The UNSC contracted Hannibal Weapon Systems to provide an up-armored variant of the Scorpion, featuring a directed energy weapon based on the M6 Spartan Laser in place of the M990 turret, and replacing the pintle-mounted machine gun with a gauss cannon similar to that mounted to Hannibal's up-armored Mantis.

One Corp Scorpion was owned by the Liang Dortmund corporation and was present on Meridian when it came under attack by Promethean forces in October, 2558. Governor Sloan authorised Fireteam Osiris to use the Scorpion to assist his own security forces with the defence of the colony, releasing it from its corporate operator, Billy.^[5]

At least one M820 Scorpion was accidentally caught in the slipspace wake of Guardian 3209 on its way to Genesis during the Battle of Genesis, and was encountered by 031 Exuberant Witness who offering it to Fireteam Osiris their mission to retrieve the John-117 and the rest of Blue Team from Cortana.^[6]
