The '''M820 Main Battle Tank''' ('''M820 MBT'''), commonly known as the '''Scorpion''', is the [[United Nations Space Command]]'s primary [[Tank|main battle tank]], introduced in [[2557]]. Manufactured by [[Chalybs Defense Solutions]],{{Ref/Reuse|universe}} the M820 Scorpion is the successor of the [[M808 Scorpion|M808 model]] used throughout the [[Human-Covenant War]].{{Ref/Site|Id=CFTanks|URL=https://www.halowaypoint.com/en-us/news/canon-fodder-a-time-to-give-tanks|Site=Halo Waypoint|Page=Canon Fodder - A Time to Give Tanks|D=14|M=07|Y=2021}}

==Overview==
===Design details===
The M820 Main Battle Tank is similar in most respects to its predecessor, the [[M808 Scorpion]]—it is a lightly built, highly mobile weapons platform, utilizing four independently operating tracked bogies for high maneuverability on rugged terrain, and features a low hull profile with a highly placed cannon, with a cuppola pintle-mounted crew-serviced [[machine gun]] 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&nbsp;mph). However, it does not exchange mass for armor protection, retaining its survivability. 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.{{Ref/Reuse|Enc22}}{{Ref/Reuse|universe}}{{Ref/Game|ID=REQ|H5G|List of REQ cards|REQ Card|Detail=Scorpion Description|Quote=Main battle tank armed with a heavy cannon and pintle-mounted heavy machine gun. This new iteration of the storied Scorpion is half the mass of the old M808 yet has nearly identical firepower and armor protection.}}

===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.{{Ref/Reuse|universe}} The [[ONI Scorpion|variant]] used by Office of Naval Intelligence [[ONI Security|security forces]] uses an experimental ammunition,{{Ref/Reuse|CFTanks}}{{Ref/Game|Id=REQONI|H5G|List of REQ cards|REQ Card|Detail=ONI Scorpion Description|Quote=ONI spares no expense with its "security" Scorpions, outfitting them with experimental ammunition using the latest energetic propellants.

== Development and operational history ==
Following the loss of [[Chalybs Defense Solutions]]' facilities on [[Meridian]] in [[2551]], [[Acheron Security]] assumed production of the [[M808 Scorpion]]. Chalybs introduced the M820 MBT as the successor to the M808 in 2557. Though the M808 continued to serve in UNSC Army and Marine Corps armored units after 2557, the M820 Scorpion began to replace older models after its introduction.{{Ref/Reuse|universe}} By October 2558, the M820 had replaced its predecessor in [[War Games]] simulations aboard {{UNSCShip|Infinity}} among its Spartan forces.{{Ref/Game|H5G|Scorpion in-game vehicles}}

Chalybs offers a number of variants - UNSC armored units operated the baseline Scorpion, as well as Tundra, Urban, and Woodland variants with camouflage paint schemes and improved armor, while ONI operates its own Scorpion variant for its [[ONI Security|Security forces]] which featured superior armor and used experimental rounds to improve lethality. Chalybs also offers a civilian variant of the Scorpion for private military contractors, the Corp Scorpion, which features superior armor to the baseline model. 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 [[HRUNTING/YGGDRASIL Mark IX Mantis|Mantis]].

At least 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]] authorized [[Fireteam Osiris]] to use the Scorpion to assist his own security forces with the defense of the colony, releasing it from its corporate operator, [[William Khaleed]].{{Ref/Level|H5G|Glassed}}

One M820 Scorpion was accidentally caught in the slipspace wake of [[Guardian#Known Guardians|Guardian 3209]] on its way to [[Genesis]], and was encountered by [[031 Exuberant Witness]] during the [[Battle of Genesis]]. She offered it to Fireteam Osiris during their mission to meet up with [[John-117]] and the rest of [[Blue Team]] at the [[Gateway]].{{Ref/Level|H5G|Genesis (level)|Genesis}}
