Crassus

The Crassus Armoured Assault Transport is a super-heavy transport tank of the Imperial Guard. The Crassus is named after one of Lord Solar Macharius' greatest generals during the Macharian Crusade, Borgen Crassus, who had remained loyal to the Imperium even during the grim and bloody Macharian Heresy that followed after the Lord Solar's death. The Crassus, along with the Dominus Heavy Siege Bombard and Praetor Heavy Assault Launcher weapon systems are STC data constructs found on the recently re-conquered Forge World of Zhao-Arkkad. After the planet was re-consecrated into Imperial service the STC data cores were found deep inside the vaults of the once nightmarish realm.

In The 41st Millennium
Even though the Crassus is a relatively new addition to the arsenal of the Imperial Guard it has already become famous for its heavy amour and firepower, and is becoming widespread in the southern and western regions of Segmentum Tempestus and after only a few centuries the Crassus design is now being constructed on Forge World Lucius and is used to resupply forces that are guarding the area around the Eye of Terror. The Crassus is capable of transporting up to 35 soldiers in its expansive armoured hold, and is also able to carry up to two Cyclops Demolition Tanks.

Known Users of the Crassus Armoured Assault Transport

 * Imperial Guard - The Crassus is becoming widespread throughout the Imperial Guard front-line regiments.

Armament
The Crassus is heavily armed with 2 forward-mounted Heavy Bolters and 2 sponson-mounted Heavy Bolters, and every weapon can be replaced individually with a Heavy Flamer, an Autocannon, or a Lascannon. This allows the Crassus to be equipped with up to four different weapons at once. The Crassus can also replace the sponson weapons with additional armour plates for added protection. The vehicle is also able to be outfitted with a Pintle-mounted Heavy stubber or Storm Bolter for extra firepower, a dozer blade, searchlight, and smoke launchers for additional uses.
