The All Terrain Scout Transport Mark IV,[1] sometimes as just AT-ST IV[1][2] and as Mark Four transport,[2] was a reengineered All Terrain series walker, it served as the successor to the Mark III and AT-STs that follow it.[1] It was mainly used as heavy ground support, patrol, reconnaissance, and light anti-vehicle walker by the Eclipse Army.[1]
This walker was given extra armour plates, shielding as well as heavier laser cannons to deal with any type of infantry, light vehicles as well as speeders.[1] Armed with twin TX-4 heavy tri-laser cannons, HK-5X point-defense cannon and an advanced shield generator, the AT-ST Mark IV was able to hold its own against almost all walkers of its class, excluding AT-ATs.[1]
