Rail Weapons - Notable Rail Weapons: Rail Rifle - A potent weapon, the Rail Rifle makes use of the same technologies as the larger Railgun and Heavy Rail Rifle, albeit on a smaller scale so that it is infantry-portable. Possessed of an impressively long range and ability to deal great damage, the Rail Rifle's true strength lies in its armour penetration capabilities. The Rail Rifle's hypersonic projectile is able to punch through even Terminator Armour with ease. As a dedicated elite infantry killer, enemy units that manage to survive a Rail Rifle fusillade often find themselves pinned down, unable to do anything in the face of such deadly fire. The Rail Rifle also proves effective when used against light vehicles. Rail Rifles have only recently been authorised for issue to frontline T'au units, having completed an extensive field-testing phase.Heavy Rail Rifle - A Heavy Rail Rifle is similar to the larger Railgun, but is slightly smaller so that it can be mounted on a T'au Battlesuit. Whilst this weapon's range and damage is not as great as its larger cousin, it is still an impressive anti-tank weapon, renowned for its effectiveness at penetrating enemy armour at extreme ranges. The XV88 Broadside Battlesuit is the only T'au unit that is armed with the Heavy Rail Rifle, and the XV88 makes use of it as a twin-linked primary weapons system.Railgun - Railguns are renowned for their capability to penetrate enemy armour at extreme ranges. The Railgun is most commonly mounted as a primary weapon on a Hammerhead gunship. Along with standard solid-shot rounds, a Railgun is also able to fire sophisticated submunition rounds, which consist of smaller projectiles that can strike a wide area. Whilst the overall damage imparted on impact with this variant of the Railgun's projectile is less than the standard shot, such submunitions are extremely useful for suppressive area fire against infantry targets.Heavy Railgun - A Heavy Railgun is a larger version of the standard Railgun and is usually only mounted on the Manta and AX-1-0 variant of the Tiger Shark aircraft. Heavy Railguns fire larger rounds at higher speeds, and these projectiles are fin-stabilised to provide extra lift, and therefore greater range when fired in-atmosphere.Starship Railgun Batteries - Despite recent T'au advances in superconductor technology, Railguns mounted on T'au starships are of such enormous size and require such large amounts of energy to fire that they are grouped into batteries and fired one barrel at a time in sequential order, ensuring that the first barrel is loaded and ready before it is charged again. T'au starship Railgun batteries are considered comparable in firepower and effectiveness to the weapons batteries of Macrocannons employed by Imperial starships.Magna Rail Rifle - The Magna Rail Rifle is a powerful variant of the kinetic Rail Weapons used by the military forces of the T'au Empire and the Leagues of Votann. It possesses a longer range and greater stopping power than previous variants of the Rail Rifle. Rare magnetic materials discovered by the T'au fleet during the Fourth Sphere Expansion were used to develop this much improved version of the Rail Rifle and the Heavy Rail Rifle since the new materials allowed the weapon's electromagnetic accelerators to generate stronger force with which to fire a projectile. The Magna Rail Rifle is currently deployed as a twin-linked prototype main weapon that has been sized up to be usable by the XV88 Broadside Battlesuit. The Kin of the Leagues of Votann also make use of the Magna Rail Rifle in a man-portable form that is deployed as a heavy weapon with their squads of Hearthkyn Warriors. The use of the weapon by both the T'au and the Leagues of Votann is likely not a coincidence, as various Kin factions have been known to enter into commercial relationships with the T'au Empire from time-to-time and have provided them with access to their more advanced technologies before, such as Ion Weapons, though what was provided was likely not up to the full Kin standard of the technology. As the Kin are the likely originators of this technology, their variant of the Magna Rail Rifle is like to be more reliable, more efficient and crafted of better materials than the similar weapon created by the T'au.Heavy Magna Rail Cannon - A Heavy Magna Rail Cannon is a potent kinetic Rail Weapon used by the military forces of the Leagues of Votann. The Heavy Magna Rail Cannon is large, vehicle-sized weapon that possesses much greater range and stopping power than its man-portable variant in the Leagues of Votann's arsenal, the Magna Rail Rifle. The Heavy Magna Rail Cannon is often deployed as a main turret weapon on the Hekaton Land Fortress, the Kin's primary main battle tank and armoured personnel carrier.
