HAVw A6 Juggernaut / Legends The HAVw A6 Juggernaut , also known as the A6 Juggernaut , Clone turbo tank , or HAVw A6 heavy assault vehicle , was an upgraded version of the HAVw A5 Juggernaut . Description . The A6 Juggernaut model was larger than its predecessor . It measured 30 . 4 meters in height and 49 . 4 meters in length . Its interior space was greatly increased to allow for up to three hundred troopers and equipment , a complement of close support craft such as speeder bikes and light airspeeders , or a mix of both . A combination of twelve crew members were required to pilot and control the massive vehicle , although with an automation package , that requirement could be reduced to just two pilots . With thick , thermally superconducting armor ( capable of absorbing enemy fire and dispersing heat over a wide area ) and a heavier load , the A6 Juggernaut could only achieve 160 kilometers per hour , and the turning issues of the A5 model were magnified with the A6 . The slowness required for negotiating turns encouraged the A6 ' s use on open terrain rather than urban battlefields . Weapons systems were also upgraded to include a heavy laser cannon turret , a rapid repeating laser cannon , two medium antipersonnel laser cannons , two twin antipersonnel blaster cannons , and two turreted projectile launchers , loadable with variable - yield concussion grenades for close support or missiles added for anti - armor firepower . Missile range was 30km . Against an unshielded target , a Juggernaut could deliver the heat of a nuclear bomb into a small area . From a small pod above the vehicle ' s back , a spotter kept lookout for enemy forces . Though there was a large view of the area , he was an easy target for hostile troops . This observation mast could be retracted when not in use . History . The A6 model saw its heaviest use in service of the Galactic Republic during the Clone Wars . Due to a flawed direct - delivery system maintained by Kuat Drive Yards during the conflict , some A6 Juggernauts also fell into the hands of the CIS . HAVw A6 Juggernauts were used fairly extensively in the Battle of Kashyyyk alongside AT - APs , where they went up against enemy NR - N99 tank droids and DSD1 dwarf spider droids . After the Clone Wars , the Imperial Army developed sleeker and more versatile combat vehicles . The various Juggernaut models were gradually phased out , and during the Galactic Civil War , they primarily served on battlefronts in the Outer Rim . Some fell into the hands of the Rebel Alliance . According to Imperial - turned Rebel General Crix Madine , the HAVw A6 Juggernauts tended to break down . It appears that the HAVt B5 Juggernaut served as its successor , even though its purpose was different . A6s were deployed in the Battle of Hoth . By 13 ABY , they were one of a number of Clone Wars - era Galactic Republic vehicles being used by the Restored Empire faction of the Imperial Remnant . Later - generation AT - ATs would borrow certain design - elements from the Juggernauts . Behind the scenes . The Juggernaut ' s designs entered the Expanded Universe via Joe Johnston ' s sketches of an unused heavy assault vehicle intended for " " . It and its role in the film was replaced by the AT - AT . When chosen to appear in " Revenge of the Sith " , the realization of its scale and weapon systems greatly outstripped those imagined by the Expanded Universe , being roughly larger by a scale factor of two , or eight times larger in volume . To accommodate this , the version that appears on - screen was denoted as the A6 model , with the smaller , EU model already denoted as the A5 . The " Clone Turbo Tank " name possibly arose because at the time of the release of the prequels , Toy Biz owned the rights to produce toys named " Juggernaut " ( as they had the Marvel license ) . Though Hasbro now has the rights to this name , the 2009 toy was still named Clone Turbo Tank . LEGO has also made 3 models of a Juggernaut , all called " Clone Turbo Tank " . The first Clone Turbo Tank Lego set 7261 , released in 2005 , is an A6 Juggernaut model , as seen in " Revenge of the Sith " during the Battle of Kashyyyk . The second set 8098 , released in August 2010 , is a Juggernaut model with specifications similar to that of an A5 Juggernaut , as seen in the " Clone Wars " series during the Battle of Felucia . The third set 75151 , released in May 2016 , is based on the A6 Juggernaut from " Revenge of the Sith " during the Battle of Kashyyyk , similar to the first model .
