The DC-15A Blaster Rifle was the weapon of choice for the Republic's clone troopers in the Grand Army of the Republic. It was a larger, more powerful alternative to the DC-15S Blaster Carbine. After the Clone Wars ended, the rifle continued to see service within the Galactic Empire.
Manufactured by BlasTech Industries, the DC-series was a range of plasma weapons used during the Clone Wars. While the use of blasters freed a clone trooper from the need to carry projectile ammunition, the inherent instability of plasma gas meant the DC-15A was notoriously difficult to aim. For the well-trained clones of Kamino, however, this was not a problem. The blasters were powerful and deadly in the hands of the specially trained clone troopers.
The weapon's tibanna gas cartridge carried enough gas for approximately 500 shots, depending on the power settings of the weapon (the highest power setting shot 500 rounds per cartridge). Its power-charge magazines ionized the gas into charged plasma within its ignition chamber. These bolts would then be accelerated out of the rifle electromagnetically. Because of the hyper-ionization, the blue plasma bolts were fully capable of shredding through droids and vehicles alike, and was fully automatic.
The DC-15 could interface with the helmets of clones to provide a video gunsight on the clone trooper's helmet display. Mounted on a tripod, the maximum effective range of a DC-15A was 10 kilometers. On maximum power, a shot from a DC-15A could leave a 0.5 meter hole in any ferroconcrete wall.
The blaster could be outfitted with ascension cables to climb up walls or cliffs. Even though a powerful weapon, many clones preferred to use the lighter, more compact DC-15S since it was less bulky and was handier in close quarters, thus creating some sort of rivalry between the weapons.
