The M2032 Sabertooth is a third and fourth-generation main battle tank in service with the Imperial Layartebian Military, the Royal Cottish Military, and the military of the New African Republic.

Development

Origins

Development of the M2032 Sabertooth began in earnest in the late 1980s. The chief tank in service with the Imperial Layartebian Military at this time was the M1A1 Abrams, which was built in large numbers beginning in 1980 after a length design process that was hindered by the Second Layartebian Civil War. In 1989, designers in the Layartebian Defense Corporation saw the M1 Abrams as a viable tank throughout the rest of the century but they envisioned newer emerging technologies beginning in the year 2000 that would make the M1 Abrams quickly obsolete.

Looking to tanks of the world, the Ministry of Defense announced a plan to replace the M1 Abrams in the 2004 - 2008 date range with a new, fourth-generation main battle tank. As an interim solution, the M1A1 Abrams began an upgrade program in 1992 to the M1A2 standard. In 1992, the Next-Generation Battle Tank (NGBT) program began with three prototypes. Focusing on emerging technologies and using the program as a way to flesh out these design, the NGBT program was allotted a considerable amount of funding from the earliest stages of its conception.

The first prototype came from the Armed Republic of Soviet Bloc, the Empire of Layarteb's westernmost neighbor, a nation that stretched for nearly the entire North American Midwest and was years ahead of the Empire of Layarteb in tank design. Their entry was the ST-39K1 Mekhev II, a fourth-generation, brand-new battle tank that traced its lineage through several advanced designs dated back to the early 1970s. The ARSB was considered the zenith in tank design at this time and the ST-39K1 would have been adopted had domestic troubles not caused the collapse of the country. What few ST-39K1 examples were produced by the ARSB were bought and stored by the Empire of Layarteb to prevent this technology from falling into hostiles hands. The ST-39K1 was eliminated from the competition in 1994 due to these domestic troubles.

The second prototype was the M1A3 Abrams, which took the M1A2 Abrams upgrade and incorporated features that the ARSB tanks incorporated, chiefly among them a 120-millimeter electronic-thermical chemical cannon (ETC). The redesigned M1A3 Abrams featured numerous upgrades for urban combat survivability, more advanced sensors, an active protection system, and the use of fiber-optic lines, reducing weight by 2 tons. However, the M1A3 Abrams was still based off of the M1 Abrams chassis and thus it was not destined to be a winner. It was eliminated in 1996.

The third prototype was the M2032 Sabertooth, which began its life as a tank designed and similar to the Leopard 2A4 main battle tank. Dimensionally similar to the Leopard 2A4, the M2032 Sabertooth did not feature the angular design of either the M1 Abrams or the ST-39 but it did feature additional levels of armor protection beyond what the Abrams or the Leopard could offer. It opted for a derivative of the Abrams' gas turbine engine but with more power. Additionally, it featured extensive use of remote weapon systems (RWS) for crew survivability and a larger, 125-millimeter ETC cannon. However, the M2032 Sabertooth was never considered a true fourth-generation main battle tank. Instead, it was labeled as a 3.5-generation main battle tank. Unfortunately, by 1998, the M2032 Sabertooth was the only contender remaining and it was decided to put the M2032A1 Sabertooth into service as an interim solution until a true fourth-generation main battle tank could be designed.

When the M2032A1 Sabertooth entered service in 2000, it did so alongside the M1A2 Abrams. Because the M2032A1 Sabertooth was not considered a fourth-generation battle tank, it could be approved for export to both Tier I and Tier II allies, albeit with some downgrades.

Design on the fourth-generation Sabertooth continued from 2001 until 2009, when the M2032A2 Sabertooth entered service. As a true fourth-generation main battle tank, exports for the M2032A2 would be restricted only to Tier I allies. The design of the M2032A2 retained the power pack, transmission, suspension, and armament of the M2032A1 but the armor and hull design were radically different and improved. The design of the M2032A2 necessitated the development of a specialized production line due to the production process of the lower hull, which is a solid forged piece, done to make the M2032A2 all but invulnerable to IEDs and blast-based, anti-tank mines. The M2032A2 began to replace M2032A1 variants in service in 2009 and became the only variant in service by 2014.

Other variants of the Sabertooth that have been designed include the M2040 Wolverine II, a bridging vehicle; the M2041 Kodiak, a combat engineering and armored recovery vehicle; and the M2060 Buzzsaw, an urban combat vehicle. All three of these designs are based off of the M2032A1 Sabertooth. Since the retirement of the M2032A1 Sabertooth, spare parts for these variants and combat replacements have come from the existing stock of M2032A1 Sabertooth tanks.

Production

Production on the M2032A1 Sabertooth began in 1999 at the same factory where the M1 Abrams was designed in Lima, Ohio. Approximately 10,000 M1 Abrams tanks had been produced and some 6,000 would have to be replaced with the M2032A1 Sabertooth. Production ran for six years from 1999 to 2005, during which time the 6,000 necessary units were produced. A second production line was opened in 2001 with only 75% capacity to construct export tanks. This line ran until 2005 as well.

The M2032A1 Sabertooth was produced in three different versions. There was the basic package, M2032A1 Sabertooth used by the Imperial Layartebian Army, identified internally as the M2032A1A. The Imperial Layartebian Marine Corps ordered the M2032A1B, which featured a revolver-type autoloader. Export customers received the M2032A1E Sabertooth, which featured less capable sensors and a 120-millimeter/55-caliber smoothbore cannon, the same cannon as used on the Leopard 2A6.

From 2005 to 2008, the Lima Army Tank Plant was converted to produce the M2032A2 Sabertooth. Both lines were upgraded to be able to produce the M2032A2 and production began in November 2008 and continues to the present time. In 2013, the export line was taken offline and reactivated in 2014 to produce the limited numbers of the M2057A1 Super Sabertooth that had been ordered. Production on the M2057 is expected to continue through 2017 while production on the M2032 is expected to continue through 2020.

Upgrades

There are currently no upgrade packages finalized for the M2032A2 Sabertooth. Because of the tank's newness, any upgrade packages will likely not be seen until after 2020.

The singular "upgrade" to the M2032A2 Sabertooth is the larger and heavier M2057A1 Super Sabertooth heavy battle tank, which features a much larger gun, more armor, and an improved suspension. The M2057 is designed to defeat modern, third-generation and 3.5-generation main battle tanks.

Design

External

Externally, the M2032 Sabertooth is dimensionally similar to the Leopard 2. The M2032A1 Sabertooth is similar to the Leopard 2A4, the last Leopard with a flat-faced turret while the M2032A2 Sabertooth is similar to the Leopard 2A7 with an angular turret.

The traditional layout of a main battle tank was adhered to with the M2032. It features a rear-engine and a low profile. The chassis of the vehicle is 26.5 ft (8.07 m) in length, 12.5 ft (3.81 m) in width, and 9 ft (2.75 m) in height. The Sabertooth is 9.94 ft (3.03 m) in height with its remote weapon systems. Either version is fully capable of being transported in the C-17 Globemaster III.

The M2040 Wolverine features only the chassis of the M2032 Sabertooth, opting for the bridge instead of the turret and the M2041 Kodiak features a high capacity crane as well as a bulldozer blade for demining and obstacle clearance operations. A secondary variants features an excavator arm.

The M2060 Buzzsaw features a much smaller turret with little change to the overall height of the vehicle. The smaller turret is used because of the smaller cannons used on the Buzzsaw. This does translate into weight reduction.

The primary and chief design difference between the M2032A1 and the M2032A2 design, at least as the hull is concerned is the lower hull portion. On the M2032A2 Sabertooth, the lower hull is a solid forged. The bottommost part of the hull features a shallow "V" angle for blast deflection and it does not feature an escape hatch, which proved less than optimal in virtually all situations. Hatches on the M2032A1 were rarely used due to their placement and the time an individual required to both access and to traverse them. The solid forged lower hull provides exceptional resistance against blast-based, anti-tank mines and IEDs while providing better fording capabilities. The weight savings for this solid forged piece are negated by the M2032A2 Sabertooth's additional armor.

Internal

Within the Sabertooth, sit four crewmen. Conditions within the Sabertooth are like most battle tanks, relatively cramped. There is no room for an additional, fifth person but each crewman's station provides more room than in the M1 Abrams. The inside of the tank is fully climate controlled and fully protected against NBC threats. Positive pressure is generated within the inside tank when the NBC systems are operating, preventing any air from breaking into the vehicle.

Electrical systems of the Sabertooth are EMP-hardened and the tank's main computer systems are linked to the greater Layartebian battle network. Owing to the new age of cyber warfare, the Sabertooth's electronic systems offer triple redundancy and dynamic protection against digital threats. Regular updates to the software can be conducted with no more equipment than a laptop and 30 – 90 minutes, depending on the connection speed and the scope of the upgrade.

An auxiliary power unit allows the Sabertooth to run its systems in a stationary situation using the tank's fuel supply.

Additional amenities inside of the Sabertooth include an AM/FM radio with an auxiliary input to allow for recreation during off periods. Due to the noise generated by the tank's systems, this amenity if virtually impossible to hear when the vehicle is on the move or running its engine. The vehicle is also equipped with a loudspeaker to use in crowd control scenarios or when addressing soldiers. On the rear of the tank is a communications uplink in a protected box. A simple two-handset to the tank's intercom system is provided as well as an audio jack for soldiers wearing headsets.

To protect the crew, padding is used on various parts of the tank where it is deemed likely that a head injury could occur in the event of a collision or a projectile strike. Ammunition is stored in a protected locker designed to blast outwards in the event of an impact, rather than inside. Harnesses are included as well. An under vehicle escape hatch is available in the M2032A1 only.

Powertrain

The Sabertooth is powered by the VT-G2-1900 Gas Turbine Engine, which produces 1,900 hp (1,417 kW) at 3000 rpm and 3,455 ft·lbf (4,684 N·m) of torque at 1000 rpm. The Super Sabertooth uses the more powerful VT-G2-2180 Gas Turbine Engine, which produces 2,180 hp (1,625 kW) at 3000 rpm and 3,995 ft·lbf (5,416 N·m) of torque at 1000 rpm. The VT-G2-1900 weighs 3,000 lb (1,361 kg) while the VT-G2-2180 weighs 3,050 lb (1,383 kg).

The decision to maintain the gas turbine engine was largely due to the reduced aural signature versus a diesel, the fewer parts associated, and the need for significant power. Both gas turbines are multi-fuel systems designed to run on jet fuel or diesel gasoline. On both engines, due to the susceptibility of foreign object damage, a series of filters are installed that trap over 99% of foreign particles. The advantage of the gas turbine engine gives the Sabertooth a power-to-weight ratio in excess of most third-generation tanks.

Coupled to the gas turbine engines are semi-automatic transmissions. Clutchless systems, they require the driver to shift gears up and down. The decision to maintain a semi-automatic system versus an automatic system was due to ability of a driver to maintain the tank within the power bands, allowing for quicker acceleration and phased deceleration. In the Sabertooth, there are six forward gears and in the Super Sabertooth, there are seven. Both vehicles have two reverse gears, with the second being unregulated.

In the M2032A1 Sabertooth models, the suspension is a traditional torsion bar. Rugged and compact, the torsion bar of the M2032A1 Sabertooth allows for adjustable height ride with the simple adjustment of various bolts.

On the M2032A2 Sabertooth, the torsion bar was removed in favor of a hydropneumatic, active suspension. The system allows for better recoil absorption, a smoother ride, more agility, and better height adjustment. The same suspension is carried over to the Super Sabertooth.

The running gear of the Sabertooth is relatively common. There are seven road wheels with four return rollers per side. There is an idler wheel in the front and a drive sprocket in the rear. The tracks of the Sabertooth are virtually identical to those on the Leopard 2, which is considered the fastest and most mobile of the third-generation tanks.

Systems

The Sabertooth is not just a tank with a gun. It is a sophisticated battle platform. It features an integrated sensor and self-defense system. For self-protection, the Sabertooth uses the AN/VLQ-30 Modular Integrated Self-Protection System or MIPS. The MIPS system combines passive and active defeat systems such as electronic jammers and smoke systems with hard-kill systems. Additionally, some models feature a microwave module that allows for directed-energy against incoming projectiles or personnel. Export models of the M2032A1E Sabertooth feature a downgraded variant of the MIPS with will capabilities; however, the M2032A2C features the same systems as the M2032A2.

For sensors, the Sabertooth uses the AN/VSQ-31 Modular Integrated Detection System or MIDS. The MIDS features an array of sensors. At the most basic level there is an electro-optical, thermal sensor with low-light and night vision capabilities. There is a laser designator and rangefinder for targeting, a LIDAR for obstacle avoidance and 3D target classification, a millimetric-wave radar for self-defense and target detection, and a seismic sensor for short-range detection when the vehicle is powered down and running solely on its APU. Like the MIPS, the M2032A1E features a downgraded model of the MIDS. The M2032A2C features the same systems as the M2032A2.

Armor

The meat of why the M2032A2 Sabertooth is a fourth-generation tank is its armor. Outside of its advanced electronics and sensors, the Sabertooth also features advanced armor. Rather than the traditional Chobham armor of the M1 Abrams, the Challenger 2, and the M2032A1 Sabertooth, the M2032A2 Sabertooth opts instead for an entirely new schematic of modular, ceramic composite armor.

Using nano-crystal steel, the M2032A2 Sabertooth uses carbon nanotube metal matrix composites (CNT-MMC) materials. These materials offer a very high tensile strength without the brittleness normally associated with hardness. Modeled after AMAP armor, the composite armor blends together new, advanced steel alloys, aluminum-titanium alloys, nanometric steel, ceramics, and nano-ceramics with more traditional tungsten and depleted uranium. The result is an armor layer that requires significant less thickness to provide the same degree of protection. As a result, this new alloy is over two times as protective as traditional RHA.

Unfortunately, the armor is also very expensive and this contributes significantly to the high cost of the tank. The main armor of the M2032A2 Sabertooth is unchanged on its variants with only more of it added to the Super Sabertooth. The result is a tank that provides more protection against kinetic and chemical energy projectiles than anything in its class does, as evidenced in the vehicle's combat performance.

The armor of the M2032A2 Sabertooth works on five stages. The initial and outermost layer of armor aims to slow down, deform, blunt, or otherwise defeat the physical round. It uses a honeycomb layout to provide additional strength. The second layer functions on the same purpose while also adding the need to absorb the energy of the impact itself. Rather than honeycombing the pattern, the second layer is arranged in a scale configuration with overlap. The third layer is the most important as it will take the most effects of an incoming round. It is meant to slow down and further deform the projectile, removing its penetration capabilities while also evenly distributing the energy of the impact evenly to prevent further penetration. The fourth layer is a mere backup layer. This layer also provides defense against radiation. The fifth and final layer provides a further backup while acting as the final block for radiation. It also provides fire resistance.

In some cases, the Sabertooth can mount additional, add-on systems. The most common add-on is ERA or explosive reactive armor. Built in bricks 4.13 in (10.49 cm) wide, 9.05 in (22.98 cm) long, and 3.75 in (9.52 cm) weighing 28.5 lb (12.93 kg) each, ERA provides an outermost layer of protection and is very effective against explosive weapons. Using a shaped-charge, the ERA bricks detonate upon impact, forcing the blast outwards to defeat an incoming round. It is not considered a safe application when combat soldiers are in close proximity.

To counter that, the Sabertooth can also mount non-explosive reactive armor or NERA. Safe to use around troops, NERA is not as effective as ERA is since it does not use an explosive to destroy the incoming round. Instead, NERA is largely consisting of high-density rubber, which is inert. There is, however, one major advantage of NERA over ERA, it cannot be defeated with a tandem charge warhead. NERA blocks are roughly the same size and weight as ERA blocks.

Additional add-ons include a Rear Protection Unit or RPU. The RPU is an add-on kit made of parallel bars of "slat armor" made of an alloy consisting of Tungsten Carbide, Aluminum Oxide, and hardened ceramics. It is usually spaced approximately 12 in (30.48 cm) to 20 in (50.8 cm) from the hull of the tank and effectively detonates HEAT warheads before they rear the hull of the tank, rendering them useless. It has been shown, in combat applications, to provide significant protection to the engine compartment. It weighs a mere 3,425 lb (1,554 kg). Almost all Sabertooths fit the RPU.

There is a Projectile Attachment Cage or PAC as well. The PAC is an add-on kit extremely similar to the RPU except that instead of simply protecting the engine compartment, it protects the entire hull of the tank. It is spaced out effectively to protect the skids and the turret cupola but is engineered and shaped to not get the way of the skid mounted missile launchers and the turret itself. It is made of the same alloy as the RPU and is laid out in exactly the same way. It weighs 10,285 lb (4,665 kg). This is often not fitted but is available for urban situations.

Lastly, the Sabertooth can mount RPG Protection Panels RPP or RPP-L. These are rarely fitted and aim to protect the running gear of the tank to prevent against a mobility kill. They are panels made of a mixture of Depleted Uranium, highly compressed ceramics and porcelains, aluminum oxide, and tungsten carbide. The interior of the panels are arranged in a crisscross pattern in the center with a web of scales of both ceramics and porcelains. Ceramic foam is injected into the open spaces and aluminum oxide is used to coat all scales and layers. Tungsten carbide and Depleted Uranium make up the rods. Lastly, they are encased in RHA. They are far heavier than the PAC and each skid can hold up to 4 of these panels, each weighing 4,250 lb (1,928 kg). They would add a total of 34,000 lb (15,422 kg) to the tank. The RPP-L I just 1,062 lb (482 kg) and eight of them are required. The total increase using the RPP-L is 8,496 lb (3,854 kg).

Armament

Main Gun

The Sabertooth would be nothing without its main gun. Despite the presence of advanced armor, a powerful engine, and highly sophisticated sensors, the Sabertooth's true advantage lies in its main gun. For domestic variants, the Sabertooth uses the M360A2 125mm/52-caliber ETC cannon.

Export variants of the M2032A1 Sabertooth, the M2032A1E, used the Rheinmetall 120mm/44-caliber smoothbore cannon with the same projectile load.

Export variants of the M2032A2 use the M360A1 120mm/44-caliber ETC cannon.

As an ETC gun, the M360A1 and the M360A2 provide the Sabertooth with the ability to fire a variety of rounds out to ranges of 8 km (5 mi) and missile rounds further to 12 km (7.5 mi) or greater. Canister rounds are effective out to 700 meters. The cannons can also fire gun-launched missiles. Depending on the version of the Sabertooth can carry between 40 and 48 projectiles and missiles.

The Sabertooth's cannon is completely stabilized and it can fire accurately at the vehicles top speed and on any road condition. The turret offers total, 360° traverse with an elevation range of -10° and +30°. The cannon is ranged and aimed using the vehicle's laser rangefinder. However, it can also be fired using targeting information from any of its sensors.

The original M2032A1 did not feature an autoloader and as a consequence, rounds had to be loaded by hand. The M2032A1B introduced a revolver-based, 6-chamber revolver. The loader has complete control over this system but he can be overridden in the case of incapacitation by the gunner or the commander. The revolver normally rotates counter-clockwise. As a round is inserted, the revolver rotates to the next chamber. The loader then puts in a round in the empty chamber to ensure that the revolver's chambers are always ready. The revolver can rotate very quickly and in the event a round is needed in the opposite direction, the revolver can rotate clockwise. On the M2032A2 and the M2057A1, the autoloader was made standard.

On the M2057A1 Super Sabertooth, the cannon is uprated to the M360A3 140mm/48-caliber ETC cannon. The added power of the cannon is to ensure tank-destroying capabilities. The cannon can also be used in indirect fire applications up to ranges of 15.3 km (9.5 mi). Because of the larger projectiles, the Super Sabertooth can only carry 36 total rounds.

The M2060A1 Buzzsaw gets its name directly from its main armament. In a modified turret, the Buzzsaw carries two M363A1 Swiftkill rapid-firing autocannons. Fed by a magazine of 610 rounds, the guns can fire up to 1,000 rounds per minute. Normally, they fire high-explosive incendiary ammunition designed to be used in a suppressive nature against soft targets but they can also fire AHEAD or APDS rounds. The Buzzsaw can destroy lightly armored vehicles but it is not meant to take on an armored fighting vehicle or another tank. During testing, one M2060 Buzzsaw unleashed its entire ammunition load into a building, causing the top half of the building to literally collapse off of it. An observing general commented that the M2060's guns were like a "buzzsaw" and consequently, the name stuck.

Secondary Armament

The Sabertooth comes equipped with two main secondary systems, a co-axial heavy machine gun and the skid missile launchers. Export models of the M2032A1E do not mount the skid missile launchers; although, the M2032A2C does.

In domestic variants, the co-axial weapon is an M31A2 15.5-millimeter heavy machine gun. Normally a dual-feed system, the M31A2 uses a single feed and offers a rate of fire of 600 rounds per minute. The weapon is effective out to 2,400 meters. The feed box for the co-axial gun can only hold 250 rounds due to space limitations. Three boxes are provided for stowed ammunition.

In export variants, the co-axial weapon is the M50A2 12.7-millimeter heavy machine gun. A single-feed system like the M31A2, it has an effective range of 1,800 meters but a maximum rate of fire of 1,200 rounds per minute. A selector allows for a reduced rate of 600 rounds per minute. There are 500 rounds ready and an additional 1,500 rounds stowed in three boxes of identical size to those of the M31A2.

The skid missile launchers are a unique innovation to the M2032A2 Sabertooth. Armored to prevent against projectile strikes, each skid mounts a two-barrel missile launcher oriented forward. The tank's driver has full control over this weapon system. Originally designed for the LOSAT, these now mount the MGM-251 HVKEP missile. Whereas the LOSAT was entirely unguided, the HVKEP can utilize laser, datalink, or command guidance. Because of the high-velocity of the weapon and the orientation, guidance is limited to a very short window and the engagement field of view is restricted to only 45° off of the tank's center point. The object of the missile launchers was to provide the Sabertooth with a counter-flanking ability. Should the Sabertooth have its cannon oriented a different want to engage hostile tanks and a vehicle appear on its front quarter, the missile launchers could be used to neutralize them. One missile is all it takes to destroy a tank, given the sheer amount of kinetic energy that they possess.

Tertiary Armament

Backing up the Sabertooth's main cannon, co-axial machine gun, and its skid missile launchers is an array of tertiary weaponry designed to counter a variety of threats. In place of the traditional commander's and loader's machine guns are a pair of turreted weapon systems. The M153 CROWS II RWS was chosen for both stations to provide commonality and protect both crewmen from the hazards of using said weapons in an open, ongoing battle environment, especially in an urban scenario. Both RWS systems can mount the same weapons and they offer significant variety. Because of ammunition stowage limitations though, the Sabertooth must also carry extra magazines within its turret in order to provide a usable ammunition load. The options are as follows:

  • (1) M31A2 15.5MM HMG with 200 rounds ready and 400 rounds stowed
  • (1) M35A1 7.62MM LMG with 1,800 rounds ready and 3,600 rounds stowed
  • (1) M49A1 40MM Grenade Launcher with 140 rounds ready and 280 rounds stowed
  • (1) M50A1 12.7MM HMG with 400 rounds ready and 800 rounds stowed
  • (1) M74A1 7.62MM Minigun with 5,400 rounds ready
  • (1) M307A1 25MM Grenade Launcher with 225 rounds ready and 450 rounds stowed

Normally on the Sabertooth a single HMG is mounted on the commander's RWS and an LMG on the loader's RWS. In situations where a Sabertooth might need heavier armament the 40-millimeter grenade launcher and the 25-millimeter grenade launcher can be carried. When carrying the M74A1 Minigun, the RWS features a large, single magazine with no extra ammunition stowage.

Outside of the RWS stations, the Sabertooth also mounts a dual-launcher for anti-tank guided missiles on its turret. This foldable launcher can be reloaded manually and it carries the same missiles as can be launched from the Sabertooth's main gun. Ideally, this would be loaded with fire-and-forget missiles but there are attachments for wire-guided missiles to be carried, provided they fit within the tubes.

For self-defense, the Sabertooth can carry four 6-barrel smoke grenade launchers, each loaded with 66-millimeter smoke grenades. These can be fired automatically by the vehicle's MIPS system or manually by the commander. For anti-mining operations, the Sabertooth can mount two mine-clearing blades on its front, which dig up the earth and render the mine's neutral.

Subtypes

The Sabertooth is a complex and versatile platform. Its chassis serves as the basis for five vehicles with only minor differences amount them.

The M2032 Sabertooth is the main variant and is thusly written in this article. The M2057 Super Sabertooth is an uparmored heavy battle tank sporting a more powerful engine, stronger suspension, and a more powerful main gun. Because of the larger autoloader, the M2057 only has a crew of three.

M2040 Wolverine II dispenses with the vehicle's turret and instead it mounts a deployment system for a modular bridge. The Wolverine II's bridge can be deployed in three lengths: 91 feet (27.7 m), 93.25 ft (28.4 m), and 95.5 ft (29.1 m). The width of the bridge is 13.12 ft (4 m) and each module is 2.15 ft (0.65 m) high. Each module weighs 11,025 lb (5,000 kg). The standard module length is 31.83 ft (9.7 m). Three of these are used to achieve the maximum length. It takes three, five, and six minutes to deploy the three spans and the Wolverine II has a crew of only two men. The bridge can support vehicles up to 70 tons for unrestricted crossing and up to 100 tons for cautious crossing. The Wolverine II is unarmed.

The M2041 Kodiak is an armored recovery and combat engineering vehicle. It replaces the M1 Grizzly Combat Mobility Vehicle (CMV). The M2041A1 Kodiak ARV is equipped with a high-capacity crane that can traverse 270° and lift up to 66,150 lb (30,000 kg). The crane itself is equipped with an electronic momentum limiter that makes constant adjustments to elevation, vehicle tilt, and load mass to prevent overload. The vehicle is equipped with a forward winch that is 600 ft (183 m) long. The cable is 1.5 in (40 mm) in diameter and it can support up to 77,150 lb (35,000 kg). The vehicle can carry a complete Sabertooth powerpack in a special cradle on deck and the dozer blade can be used for obstacle or mine clearance or to stabilize the vehicle during crane operation. Electric cutting and welding equipment are stored with the vehicle, it has a suspension lockout system, and a self-recovery system. The vehicle is equipped with a single light machine gun for self-defense and smoke grenades. Its towing capacity is 77 tons (70,000 kg). The Kodiak is crewed by two men. The M2041A2 Kodiak CEV swaps the crane for an excavator arm.

The M2060 Buzzsaw is an urban combat vehicle. It uses a smaller, modified turret mounting two, rapid-firing cannons. It is designed for urban warfare in a major combat environments to act in a suppression mission. It is utilized with foot infantry and it often acts as a lead element in combat situations. It carries the same secondary systems as the M2032A1 and utilizes the commander's and the loader's RWS but does not carry the foldable missile launcher. It also uses the HVKEP missiles from the M2032A2, which are used to clear blockades and as fire suppression in urban environments when range is not a limiting factor. The HVKEP missiles have a minimum range of 400 meters.

Operational History

Conquests

The M2032A1 Sabertooth entered service only towards the end of the Conquests and thus saw little to no action until 2004. Some were deployed as part of peacekeeping operations during the Cottish Flu Pandemic but none of them saw combat. In 2004, a single tank battalion equipped with the M2032A1 Sabertooth was deployed during the Cuba Campaign and succeeded in helping to capture several key targets during the four-month campaign.

Post-Conquests

The M2032A1 Sabertooth and the M2060A1 Buzzsaw both saw action following the end of the Conquests. The Buzzsaw first saw action during the Second Venezuelan Uprising in 2007 and in the subsequent Mato Grossan Wars. The M2032A1 Sabertooth also saw considerable action during the conflict, marking the final action that the M2032A1 participated in before being retired.

The M2032A2 Sabertooth received its baptism of fire in 2010 during the Goodrule War when a single tank unit was deployed in Scotland to assist Cottish forces. They participated in the Mato Grossan Wars from 2011 to 2012 and in the Sino-Layartebian War in late 2012.

Foreign Use

The M2032A1 Sabertooth has been used more extensively by foreign forces than by Layartebian forces. The Fourth Reich of North Germania utilized its examples of the M2032A1E during the civil war that broke out in 2001 and the Commonwealth of Hirgizstan used its examples during its own internal wars. Many of these Hirgizstanian tanks were picked up by the New African Republic following the collapse of the government. Following the collapse of both North Germania and Hirgizstan, the Layartebian Defense Corporation conducted a massive and expensive campaign to buy back existing examples to be used for spare parts for Layartebian tanks and to prevent them from falling into possible enemies' hands. Outside of the New African Republic, virtually all examples were recovered or, when no other choice was presented, destroyed by saboteurs.
