M112A4 ‘Spartan’ Anti-Material Gun

A ludicrously powerful handheld anti-armor weapon designed to fire 15.2mm armor-piercing, fin-stabilized, discarding-sabot rounds. Similar to the ancient 20th century Steyr IWS 2000, the Spartan’s barrel assembly is engineered to recede into the frame upon firing in order to absorb recoil, much like a tank cannon. Like its predecessor, it uses a bullpup layout. It is one of the most lethal infantry weapons ever created, capable of defeating medium armored vehicles and mechs, with a range of over 10 kilometers in an earth-like atmosphere. Able to be a equipped with a variety of specialized munitions, including cluster rounds for taking out infantry, EMP rounds for disabling electronics, incendiary rounds, and extremely expensive UAP (Ultra Armor-Piercing) ammunition that uses a core made from Hyperdiamond Composite.
