Not a true tank by any means, the Hades Breaching Drill is essentially a piece of mining equipment. Consisting of four diamantine-tipped rotary power cutters and a high-power melta-cutter, the Hades can plough through just about any surface. The Hades is used to grind through massive walls and other obstructions, the original colonists brought hundreds of Hades Breaching Drills to mine the surface of Rheelas during the waning years of the Great Crusade but before the Horus Heresy broke out. Unfortunately, when the colony ship arrived in orbit they discovered that an error on the part of the Imperial planetologist that had filed the original survey had neglected to mention that the world was 98% covered in super heated water by the intense volcanic activity and so in the early days of their settlement the Breaching Drills were retrofitted with environmental seals, ballast tanks, and cargo holds so that their crew could mine the rare and valuable exotic ores found on and more often deep beneath the ocean floor of the planet. In the intervening ten thousand years, many Hades have been lost to mining accidents or in the few wars conducted between the Hive Cities as they also double as convenient ambush vehicles. Since the fall of the Jericho Sector, most of the Adeptus Mechanicus retreated to be with their brethren on the Forge worlds of Credence and Sammech leaving a handful of Tech-Priests to carry on the tradition. None of the Hades Breaching Drills currently in service have fully functional environmental seals, most leak water or air when submerged to some degree and require the vehicles two man crews to wear bulky diving suits or diving armor to avoid being boiled alive. Most also run on locally sourced promethium, which requires them to surface periodically or run a hose attached to a float in order to maintain engine power. If the hose is severed, it likely spells doom for the vehicle to which it was attached. It is usually a -30 to hit the air hose with a Ballistic Skill attack as modified by distance. Type: Tracked Vehicle Tactical Speed: 10 m Cruising Speed: 25 kph Maneuverability: –15 Structural Integrity: 20 Size: Enormous Armour: Front 30, Side 16, Rear 11 (when armor plates are removed in order to attach a Cargo Pod) Vehicle Traits: Amphibious, Burrower (6), Enclosed, Environmentally Sealed*, Extremely Volatile, Ponderous, Searchlight, Tracked Vehicle Crew: 1 Pilot, 1 Co-Pilot/Gunner Carrying Capacity: None. However most Hades on Rheelas pull an unarmored but air tight Cargo Pod (of Average availability; AP 2) capable of holding 3 cubic meters of ore or 1,000 kg of weight, or roughly a squad of soldiers in a detachable pod that is equipped with a reusable flotation device and vox beacon so that when released it will quickly surface and begin broadcasting its location to all receivers within 10 km. Most pods are not equipped with life sustainers (Rare upgrade) and men trapped inside without access to breathable air will quickly begin to suffocate. It is possible to chain together up to sixteen Cargo Pods, however for each one that is attached the Hades suffers a -5 penalty to its Maneuverability.

Action (see O nly W ar Core Rulebook page 273), however the Hades uses the weapon profile for the rotary power cutters/melta-cutter to determine the amount of Damage. The Hades takes no Damage from Ram! Actions as they are designed to push through solid rock without slowing down. The Hades Breaching Drill may move underground via the Burrower (6) Trait (see O nly W ar Core Rulebook page 155) leaving behind it a mostly stable tunnel through which infantry can move unhindered and without the need to crouch. Tunnels cut by a Hades are not entirely stable, however, and sometimes collapse. The Hades can attack targets above it whilst it is underground by performing a Ram! Action. Adversaries attacked in this manner are Surprised.
