An Assault Drill used by an Imperial Fists Assault Centurion
An Assault Drill, also known as a Siege Drill, is a weapon used by Space Marine Siege Dreadnoughts and Centurions to breach fortifications during siege operations. The weapon is known as a Siege Drill when employed by Centurions. It drills through rock as easily as reinforced ferrocrete, which is the substance of which most reinforced Imperial bunkers and other human structures are composed. Once the drill has penetrated the wall, a Heavy Flamer built into the drill unleashes an inferno inside the bunker, killing everything within. The Assault Drill consists of three spherical drill heads which rotate rapidly to grind away any obstruction.
