The XM44 is the new Main Battle Tank of the Glizean Union, and the first tank to be built with a pure railgun. Earlier tanks either used hybrids or chemical cannons, never has a railgun-only tank been built. Its gun allows to be aimed more than 90 degrees upwards, and 30 degrees down. It's powered by a single microfusion reactor, and the railgun has 8 capacitors instead of the traditional one, allowing for a much higher rate of fire than usual, since one capacitor is used at a time to fire, while the others are recharged by the reactor. The XM-44 Was developed as a response to the Terrans' latest forcefield and armor technologies, and is due to enter service in 2263, 2 years from now.
The Sabretooth has 5 types of ammunition, of which 3 are usually loaded. A Tungsten slug in a sabot is the default ammunition, with extreme penetration power, able to pierce several tanks in a row. Next is a frangible slug, which desintegrates on impact, transfering all energy to the target, usually used to destroy forceshields before firing with armor piercing ammunition. Next is a cluster warhead, used to fight large or multiple targets at long range, such as tank formations or airfields. The tank can also be loaded with FLAK shells, if it's deployed on the exterior of spaceships to aid in defense, or if anti-air support is required. And lastly, the shotgun shell. 8 fin-stabilized rods in a sabot. As soon as the sabot comes off, the rods start to fan out like buckshot from a shotgun, allowing to hit multiple targets at once, such as a horde of Zombies, large insects or similar peskynesses.
The tank also posesses 4 RCS thrusters for low-gravity environments, and 4 retrorockets to slow down during air drops. The tracks can be fitted with magnetic pads for the use on spaceship exteriors, or similar situations. It uses metastable metallic deuterium and helium 3 as fuel.
