The Guardian Spear was the traditional weapon of the Adeptus Custodes during the Great Crusade and the Horus Heresy. The spears were halberd-like power weapons incorporating a Bolt Caster. The weapon's powerful ranged and close combat duality complemented the fighting style of this bodyguard force, giving them good capabilities in both close combat and at a distance. In battle, Custodes spin these weapons in great arcs, slaying enemies with each strike be it in melee combat or from afar.
