The DC-15A blaster carbine, also known as the DC-15S blaster, represented a blaster carbine model utilized by the forces of the Grand Army of the Republic. This weapon was a member of the broader DC-15 family of blasters. Despite being smaller than the DC-15A blaster rifle, both weapons were sometimes referred to as blaster rifles. During the Clone Wars, it was among the most frequently distributed weapons to clone troopers, seeing action in numerous engagements. Following the Republic's transition into the Galactic Empire, stormtroopers, including TK stormtroopers, continued to employ the blaster, however, the DC-15A blaster rifles were eventually replaced by the E-11 medium blaster rifle and the DLT-19 heavy blaster rifle in Imperial service.
The blaster carbine model DC-15A possessed an equivalent shot capacity to that of the DC-15A blaster rifle, but its effective range was shorter. As a standard-issue weapon for clone troopers during the Clone Wars, the DC-15A provided reliability, offering both the capability for sustained fire and slower, more accurate long-range shots. Power output could be adjusted by the clone trooper, with a low-powered stun setting available. For enhanced stability, the blaster featured a folding stock that could be extended. Additionally, the weapon could be mounted on a tripod for stable firing. The DC-15A carbine could be equipped with sniper scopes and was designed to integrate with the holographic data displayed within a clone's helmet. Furthermore, clone troopers had the option to attach ascension cables to their carbines, enabling them to scale tall structures.
Following the establishment of the Galactic Empire, the DC-15A saw widespread use among Imperial forces. During the early years of the Empire, clone troopers, along with their TK stormtrooper successors, continued to utilize the blaster. Even though it was considered outdated, Captain Rex still used one when he was training Ezra Bridger in blaster combat. Rex's carbine was noted to fire yellow-colored bolts.
