Thunderfire Cannons

The Thunderfire Cannon is a colossal, quad-barrelled artillery gun designed to excel in a static point defence role for the Adeptus Astartes. Each is capable of firing and reloading at a punishing rate, unleashing salvo after salvo of high explosive shells, pounding the enemy into oblivion. Only the brave or the foolish dare advance forwards in the face of such overwhelming firepower. Space Marines task forces strike hard and fast, and a unit that cannot maintain a rapid advance swiftly becomes a liability. For this reason, most of their support weapons are mounted on vehicle chassis that can keep pace with the rest of the force, as can be seen with the Vindicator and Whirlwind, but the Thunderfire Cannons are the one exception to the rule.
