A Leviathan Siege Claw is the standard type of Dreadnought Close Combat Weapon used by Leviathan Pattern Siege Dreadnoughts, and were developed to be even more destructive than those of other Dreadnought patterns. A Leviathan Siege Claw is designed to sever flesh and bone, slicing a Leviathan’s foe apart in a single cut. As with all of a Leviathan's close combat weapons, they also excel at tearing through the walls of enemy fortifications. All Leviathan Siege Claws incorporate an inbuilt Melta Gun.
