Shoulder-mounted weapon systems presented a multifaceted approach to armament design, typically employing attachments to the shoulder and, in many instances, the back. Their primary function was to discharge a variety of over-the-shoulder weapons, thereby enabling hands-free operation for the user. These systems often operated independently, occasionally incorporating integrated blaster technology. In other instances, they accommodated the addition or removal of separate blaster pistols. The nature of the projectiles fired from these blasters exhibited considerable diversity, ranging from lasers to even micro-missiles.
The Parwan bounty hunter known as Derrown, nicknamed "the Exterminator," was observed utilizing a shoulder-mounted blaster between 20 and 19 BBY. The mercenary figure Migs Mayfeld employed a pseudocybernetic automated weapon mounting armor attachment, which was furnished with a DT-12 heavy blaster pistol both before and during the events of the Bothan-Five incident in 9 ABY. In that same year, two individuals participating in the Hunters of the Outer Rim competition integrated shoulder-mounted weaponry into their equipment. The Human Hunter Imara Vex was equipped with a shoulder-mounted micro-missile launcher, while the KX-series security droid designated K-A0S carried a SE-14r light repeating blaster mounted on its back.
