The Knight Paladin is the archetypal Imperial Knight combat walker, usually armed with a large calibre Rapid-Fire Battle Cannon and a giant Knight-sized Reaper Chainsword. For long-ranged devastation, there are few weapons that can match or best the Knight Paladin's battle cannon. This massive barrelled weapon is equally adept at blasting apart massed hordes of enemy infantry, gunning down entire squadrons of light vehicles, or duelling a foe's artillery at long range. The Battle Cannon is capable of piercing even a true Titan's armour. Incoming firepower is blunted as the pilot shifts the directional Ion Shield towards the approaching shots. With its long strides, the Knight Paladin can reposition quickly, firing as it manoeuvres to give maximum fire support. Should enemies approach too closely, a pair of Heavy Stubbers can mow them down.
In close combat, the Reaper Chainsword or Thunderstrike Gauntlet the Knight Paladin carries makes it virtually unstoppable, able to disregard any enemy armour with impunity. The Reaper Chainswords used by Knight Paladins are described as being easily as destructive as the close combat weapons used by the larger Warhound-class Scout Titans, capable of harming even an Imperator-class Titan's armour plating.
Knight-class walkers are true relics of a human history lost now to allegory and myth. These unique machines and the mind-impulse systems that control them produce the arts and arcana of the ancient Mechanicum by a considerable measure, and to the priests of the Omnissiah they are things of sacred mystery and beauty. Questoris Knights are true wonders of the Dark Age of Technology, they are beyond the realms of all but the most learned Magos to fully understand, but due to the presence of priceless STC manufacturing units devoted to their construction on the ancient colony worlds of the Knight Households, these phenomenally powerful machines may still be replicated and maintained. The Knight Paladin and the Knight Errant were the most common patterns of Knights utilised during the Great Crusade and Horus Heresy eras, sharing the same basic design save for the armament load-out. Towering war engines, they are burnished and caparisoned in heraldic livery, and only a Titan could hope to overmatch one in single combat. These armours are little different from the ancient war machines carried to the stars by the first Long March colonists. Only the hand-forged and intricately embossed armour plating separates them from those early exo-armours, and many of these machines have fought in the defence of Mankind for long centuries, bearing honour markings from wars long since forgotten on their plating.
On the battlefields of the modern 41st Millennia, a Knight Paladin is a truly fearsome opponent. Striding swiftly across the battlefield, the Paladin's weapons lay down a withering hail of fire, after which it can deliver a devastating charge. Once amongst the foe, the Paladin strikes left and right with its Reaper Chainsword and crushes the enemy underfoot. Few opponents survive such a deadly series of attacks. Whether duelling across empty ash wastes or fighting amongst the narrow confines of a rubble-filled hive city, a Knight Paladin is an equally lethal foe. That is because the Paladin class Knight suit is a perfectly balanced combination of speed, firepower and armour -- a supreme example of combat design. Those Nobles who pilot Knights Paladin pride themselves on being able to perform any battlefield assignment with aplomb. The Rapid-Fire Battle Cannon grants the Knight Paladin the capacity to provide long-ranged fire support when needed, delivering volley after volley of massive shells onto the foe. However, while a Paladin excels in an artillery or anti-armour role, it is equally suited to close assault. The Paladin's bipedal design, agility and speed allow it to engage the foe quickly, often by moving through or over terrain that would slow down more conventional vehicles. Its Reaper Chainsword can hack through even the iron hull plates of an Ork Gorkanaut with ease, while a single thrust from the powerful servo-motors can embed the blade deep into a ferrocrete bunker, ripping apart the defensive structure as well as any occupants. A pair of Heavy Stubbers -- one projecting from a ball-turret and the other mounted alongside the mighty Rapid-Fire Battle Cannon -- give the Knight Paladin extra firepower, allowing the adamantium-armoured giant to mow down enemy infantry that manage to avoid its crushing feet.
