The M810 Deathstalker Self Propelled Hybrid Anti Aircraft gun was a heavily modified Scorpion MBT modified for anti aircraft warefare. The second major refit of the Scorpion after the Deathstalker, the Fattail (also know phonetically as the 'Sp-hag' and the 'Fatty') uses a Misriah 40mm autogun in a dual set up, complemented by eight Slamdunk SAMs with a computer guidance system that can track air targets and target them without human input. The weapon, although computer controlled, can be taken off and put over to control of the driver, for use should the system malfunction or another, more darker reason. As of late, a growing trend with gunners is to use the guns as anti-infantry guns, the high explosive shells being potent anti-infantry weapons.
