Land Raider Excelsior

When working in concert, Space Marine command tanks can secure victory within only solar hours of making planetfall in a combat zone. Orders weighed and delivered by one of the foremost tactical minds of the Adeptus Astartes galvanise those Space Marines nearby to heroic feats of war, whilst targeting Augurs relay telemetries that make each punishing volley impossible to escape. Not only is the strategic worth of these tanks hard to overstate, but they overwhelming destruction upon the foe. The Land Raider Excelsior's Lascannons swivel and track, annhilating those enemy vehicles not crushed by its forward Grav-cannon, while the Battle Barge high above unleahses the final blow. Guided by the Augur array of the Rhino Primaris, the resultant orbital bombardment hurtles out of the sky, leaving nothing but a crater in the planet's crust where a strongpoint lay moments before.
