Earthshaker Carriage

The Earthshaker Cannon is the standard heavy artillery piece used by the siege regiments of the Iron Warriors Chaos Space Marines. Its shells are packed with powerful high-explosives that will destroy nearly anything within a sizable radius. Besides its field artillery companies, the backbone of any siege regiment of the Imperial Guard are its heavy artillery companies.

The heavy artillery pieces used by these companies are the big guns, deployed well back from the front lines to provide a sustained bombardment of the enemy forces during a major set-piece engagement. Imperial heavy artillery includes the Imperial Guard's workhorse Earthshaker Cannon, and the aging Medusa heavy siege gun.

Both types of heavy artillery fire sustained bombardments, box barrages to isolate a battlefield from enemy reinforcements, harassing fire during an enemy advance, counter-battery fire to suppress enemy artillery and destructive fire at selected enemy units, all spotted for by artillery officers who serve in the dangerous duty as forward observers on the front lines.
