M9 Wolverine

The M9 Main Anti-Aircraft Tank (MAAT), commonly referred to as the Wolverine, is a half-track anti-air vehicle used by the United Nations Space Command. It is manufactured by Ushuaia Armory.

History
As its name suggests, the M9 MAAT is designed for anti-air combat. It is not a tank in the traditional sense, rather using a half-track design which enables it to operate in rough terrain; it received the "tank" moniker due to its development alongside the UNSC's main battle tanks, as well as due to its general architecture and framework. After serving in the Insurrection, the Wolverine was used to great effect in the Human-Covenant War, most prominently during military engagements on Harvest, Arcadia, Dwarka, Jericho VII, Miridem, and Troy. After the Human-Covenant War, the Wolverine was used in the Battle of Draetheus V against Merg Vol's Covenant forces.

Design
The Wolverine's primary armament is the M260 Multiple Launch Rocket System, a development of the General Support Rocket Systems that have served alongside main battle tanks since the mid-twentieth century. This weapon possesses two pods of Argent V surface-to-air missiles that are located on either side of the driver and gunner seats; the weapon can be upgraded with two additional, smaller pods. These missiles are specialized to target and deliver their warhead to an aircraft with great speed and maneuverability. The missile pods are quite large and can be reloaded via a mechanical system in the Wolverine, which stores a small supply of missiles onboard.

The laser tracking targeting systems and anti-air capabilities of the Wolverine are virtually peerless, but it can also angle its missile pods to launch missiles at ground targets, preferably stationary targets or structures; because of this, Wolverines are sometimes used to provide indirect anti-armor support when main battle tanks are unavailable. Although aircraft pose little threat, the Wolverine is quite vulnerable to ground-based anti-armor weaponry.

The driver has the use of a pivoting XM511 Heavy Grenade Launcher for defense from ground attacks. This weapon is deadly against infantry and quite powerful against light vehicles, but the Wolverine requires combined arms support for defense from heavier targets.

Variants

 * Vanguard Wolverine - This Wolverine variant is capable of detecting Cloaked enemies. In Blitz mode, this unit has the "Rush" ability, which means it suffers no deployment fatigue when deployed.
 * Arctic Wolverine - The arctic variant of the Wolverine is equipped with a modified drive-train system to allow for better maneuverability in harsh arctic regions, as well as additional insulation and region specific camouflage for sub-zero ambush tactics unknown to Covenant forces.
 * Covert Ops Wolverine - The Covert Ops Wolverine is a highly maneuverable anti-air vehicle that combines the, M260 Multiple Launch Rocket System with IR signature reduction and limited Active Camo technology.

Halo Wars
"This new UNSC vehicle has a specialized role: anti-aircraft.The Wolverine's surface-to-air missiles enemy aircraft and buildings, but its virtually defenseless against powerful enemy ground units, so you'll have to protect it. A potent counter-punch to enemy Banshees."

Available inside the vehicle depot, the Wolverine can be built when reaching tech level 3 at a price of 300 resources and two population slots per unit. It also has two upgrades:


 * Volley: Wolverines can launch a barrage attack that engages both air and ground targets. This upgrade requires 400 resources and a tech level of 3.


 * Dual Launchers: Increases the number of missile launchers for more damage. This upgrade costs 900 resources and requires a tech level of 4.

Halo Wars 2
Unlike its Halo Wars counterpart, the Wolverine has no upgrades, instead having the dual launchers by default. The Wolverine can be built at a garage for every UNSC leader. While effective against aircraft, they do poorly against infantry, vehicles, and structures. In Blitz Wolverines cost 40 energy, while Vanguard Wolverines cost 70 energy.

Trivia

 * A wolverine is a carnivorous mammal, in keeping with the UNSC's tradition of naming vehicles after real animals.
 * In Halo Wars, the Wolverine bears a swivel mount for the XM511 grenade launcher even before the weapon is installed. The grenade launcher is absent in Halo: Spartan Assault, making the vehicle defenseless against ground attacks in the level Reinforcement of the Perch.
 * The Wolverine is similar to the GDI Pitbull from Command & Conquer 3: Tiberium Wars in appearance, function, and armament. In addition to serving as an anti-aircraft unit, the Pitbull can carry a small mortar once upgraded, similar to the Wolverine's grenade launcher.
 * The Wolverine also bears a striking resemblance to the G.I. Joe missile tank of the same name, having a similar role and design.
 * In an, Halo Wars lead writer Graeme Devine claimed that the Martian factory responsible for producing the Wolverine was bombed by Insurrectionists in 2535, halting further production of the vehicle. However, Halo: The Essential Visual Guide establishes Reach-based Ushuaia Armory as the Wolverine's manufacturer and makes no mention of the insurgent attack. Even if one of Ushuaia's factories on Mars were indeed destroyed, the company would still have access to their facilities on Reach and likely other planets, negating Devine's suspect explanation.
