DC - 19 " Stealth " carbine The DC - 19 " Stealth " carbine was a blaster carbine in BlasTech Industries ' DC - 15 blaster line . The DC - 19 was equipped with a sound suppressor unit for silent operations and an optional stealth function , which used a refined tibanna gas mixture that made the DC - 19 ' s laser bolts invisible to the naked eye . However , the tibanna mixture was highly expensive , had to be reloaded after ten shots , and needed to be cooled down after each shot to prevent damage to the carbine ' s dampeners . The DC - 19 was used almost exclusively by clone shadow troopers in the Grand Army of the Republic during the Clone Wars and for a short time afterward , when the clone shadow troopers became part of the Imperial Army . Description . Part of BlasTech Industries ' DC - 15 blaster line , the DC - 19 " Stealth " carbine was a medium - sized blaster carbine that weighed five kilograms and was worth 3 , 500 credits . Although the DC - 19 had no stun setting , it did have a number of unique features , including a sound suppressor unit that allowed the user to operate the blaster in virtually complete silence . The DC - 19 also had an alternate stealth firing mode that used a refined mixture of tibanna gas , making the bolt invisible to the naked eye , a great boon to snipers . However , the invisible tibanna mix had to be reloaded after every ten shots , and there was a required cool down time between each individual shot to protect the blaster ' s dampeners from overheating . Similar technology was later used in the Nightstinger sporting blaster rifle , utilized by Imperial commando s during the Galactic Civil War . The carbine had an optimum firing range of up to forty - five meters and a maximum range of 450 meters . History . The DC - 19 was used extensively by the elite clone shadow troopers in the Grand Army of the Republic during the Clone Wars between the Republic and the Confederacy of Independent Systems . Unlike most clone troopers , who generally used the standard DC - 15S carbine , the shadow troopers used the sound suppressor unit of the " Stealth " carbine for their covert operations deep inside Confederate territory . Shadow trooper snipers also used the invisible laser bolt in the alternate tibanna gas firing mode to great effect . In 19 BBY , after the end of the Clone Wars , the Republic ' s reformation into the Galactic Empire , and the Jedi Order being declared enemies of the state , shadow troopers were absorbed into the new Imperial Army , still using the DC - 19 during the early part of the Empire ' s reign . Circa 17 BBY , Imperial Inquisitor and Dark Jedi Valin Draco took four shadow troopers — equipped with DC - 19 carbines — on an expedition to the destroyed Almas Jedi Academy , investigating a powerful Force nexus that had appeared on the planet . Draco and his shadow troopers eventually made their way down into the Academy ' s sublevels , where the Inquisitor discovered an ancient Sith holocron . However , as Draco began to examine the holocron , the group encountered several members of an armed resistance movement working for the fugitive Jedi Master Denia . The shadow troopers attempted to ambush the resistance members , but the rebels engaged the Imperial troops in melee combat and defeated them . With the shadow troopers dispatched , a Force - sensitive resistance member took one of the clone ' s DC - 19 carbines for the rebels ' own use . Behind the scenes .
