The NARWHAL (Naval Anti-personnel Railgun: Weapon Heavy Armour Light).

The NARWHAL (Naval Anti-personnel Railgun: Weapon Heavy, Armour Light) is the Lunen Regiment Squad's Heavy Weapon, operated by each squad's Heavy Gunner. It is supported by the MANTA shroud, an armoured exo-system that protects the Gunner while enabling the weapon's use. It is a hybrid of two seperate Heavy Weapon systems: A hight rate-of-fire Railgun rifle that fires the standard Lunen Rifle Lunendrinite round, and a Rapid Grenade Launcher. The system has seperate barrels for firing, with the larger-bore Grenade muzzle housed beneath the rifle. The system is extremely heavy, requiring a larger operator in excellent physical condition, as well as the exo-augmented strength of the MANTA system. Due to the turbine engine's potential instability, and the substantial risk of overheating from the NARWAHL's rapid rate of fire, NARWHAL operators are often considered to possess an obligatory lack of concern for self-preservation, and are notorious for slight mental instability.
