Thermal imploders were high explosives carried by Wookiee warriors, Imperial stormtroopers, and Rebel troopers during the Galactic Civil War. The imploder functioned by compressing and heating the surrounding atmosphere, thus creating a vacuum that provides a powerful implosion in a large radius. A thermal imploder could seriously damage a turret, an AT-ST, or kill a squad of infantry if properly used. When activated, there would be a timer of about 7-10 seconds before the first explosion erupted. The first was a non-lethal wave of fire that would then come back to the epicenter causing a larger secondary explosion. These weapons were widely employed, most notably during the Battle of Scarif by coastal defender stormtroopers to destroy the Zeta-class Heavy Cargo Shuttle SW-0608 that was assisting the rebels in assaulting the Imperial installation there.
