Somewhere above the mayhem of battle the deafening roar of massive engines echoes through the billowing smoke of fire and war. The massive tracked behemoths that already tower above the men on the field are themselves dwarfed by this mechanical monstrosity. Land Ships, previously the giants of the battlefield, pale into insignificance below the enormous belted tracks of the Alamo Class Mobile Airfield. But what else would you expect when an entire military base has been uprooted and mobilised. This is the largest, and most fearsome, beast to crawl forth from the factories of the Federated States of America.
