Fellblade - Armament: The Fellblade is armed and equipped with a panoply of weapons all but unknown to the late 41st Millennium. The tanks' primary weapon is a turret-mounted twin-linked Accelerator Cannon, a vacuum-based system that uses a complex overpressure mechanism to propel heavy shells with greater force than would be possible in a conventional cannon. So efficient is this system that very little recoil is produced, making the weapon extremely accurate and stable. Furthermore, the Accelerator Cannon is served by an advanced loading mechanism that allows the tank's commander to switch ammunition types at a moment's notice. The Accelerator Cannon fires two types of munition. The first is an anti-armour shell with a super-dense core that is capable of penetrating any known class of physical armour. The second, is a heavy, high explosive munition with a fragmentation core capable of scything down dozens of foes with single shot. Both shell types are targeted using a complex logis engine system slaved to the vehicle commander's strategium terminal, enabling him to track and switch between dozens of targets.The Accelerator Cannon is far from the Fellblade's only weapon, for it mounts several more, any one of which would be counted a main weapon on a lesser tank. In particular, the vehicle carries a pair of side sponson-mounted quad Lascannons, a system held by many veteran commanders to offer the ultimate balance between rate of fire, accuracy and armour penetration. Or the side sponsons could have two Laser Destroyer Arrays mounted. In addition to the vehicle's sponson-mounted weapons, the tank was also armed with either a hull-mounted set of twin-linked Heavy Bolters or Heavy Flamers for anti-infantry fighting, and also a single hull-mounted Demolisher Cannon for destroying enemy fortifications. The Fellblade was always equipped with a searchlight and smoke launchers, but could be further upgraded with a Hunter-Killer Missile Launcher for added firepower or armoured ceramite plating for even better protection from enemy fire, especially energy-based weapons.The vehicle could be outfitted with a variety of Pintle-mounted weapons, including twin-linked Combi-Bolters or other Combi-weapons, a Havoc Missile Launcher, and either a single Heavy Flamer, Heavy Bolter, or a Multi-Melta. There are some known variants to the standard Fellblade armament, such as replacing the turret-mounted twin-linked Accelerator Cannons with a Mega Battle Cannon and co-axial Autocannon such as those used by the Baneblade, and also replacing the sponson-mounted weapons with Heavy Bolter boxes. These were armoured pill-boxes with a Heavy Bolter placed on three sides. It is unknown if this was an officially recognised weapons loadout, a customised weapons loadout, or the result of field repairs which replaced damaged weapons with those from a Baneblade.As advanced as its weapons undoubtedly are, the Fellblade's armour and other systems are equally as formidable. The tank's armour is constructed of a reinforced metaplas alloy matched only by the armour utilised on the God-machines of the Collegia Titanica, while its engine and systems are powered by an Atomantic Arc-reactor, a system the Adeptus Mechanicus has been all but unable to replicate for many generations. Additional heavy ceramite plating fitted to a Fellblade allowed it to withstand extremes of heat and radiation. Plating of this kind was commonly fitted to orbital strike craft to enable them to withstand the rigours of "crash" re-entry from space into a planet's atmosphere, and also to certain siege vehicles to protect them from thermal energy weapons.The Fellblade was at one time often crewed by Legion Serfs, many of them individuals who were rejected during the Space Marine implantation and indoctrination process, but who were nonetheless superior to the rank and file of the Emperor's fighting forces. In the late 41st Millennium, however, such venerated war engines are only ever crewed by Space Marines, invariably the most experienced and honoured brethren serving directly under the Master of the Forge. It is only ever at the direst behest and concordance of the Chapter Master and the Master of the Forge that a Fellblade is deployed, and only in the direst of circumstances, and in almost all cases, heavy damage is all but irreparable and the loss of a Fellblade a tragedy for the entire Chapter.
