The Argenta Self Propelled Anti Tank Artillery Vehicle Model-98, also known as the Instigator, is a Machina vehicle built for anti-tank purposes. The vehicle has a box-like body with a slightly sloped glacis plate, mounted on a pair of tracks. The main armament of the vehicle consists of six God Hammer anti-tank missiles. These ATGWs are unusually named, as they are not, as sometimes mistaken by UNSC soldiers (much to the offense of the Machina), named for a hammer wielded by a deity, bet rather the idea of deicide, the literal hammering and crushing of a god, a concept popular with the atheistic and antireligious Machina, but offensive to many soldiers of other AUR races.
