Cyboar

The rider counts as Cavalry – see page 93 of the Warhammer 40,000 rulebook. A Cyboar is extremely tough, reinforced with steel plates and bionic limbs, has its tusks replaced by blades and has an injection device which pumps it full of stimulants. Because of the toughness of the Cyboar and its value as cover, the rider counts as being in 'eavy armour and gets a 4+ armour save. The bionic augmentation makes the Cyboar a potent additional weapon, granting the rider an additional close combat attack. During assaults and sweeping advances, models mounted on a Cyboar that pass through difficult terrain are killed on 1-3, as the Cyboar has a tendency to butt rocks and trees.
