This reptile mercenary succeeded at solving another out-of-control-robot problem, that kept the locals of this area terrified.
This isn't the most dangerous one he's faced so far though!
This pic also displays a kind of technology that got widespread in recent times in known space: Ring guns, which are an evolution of the classic railguns, fire a cilindrical ring projectile using electromagnetic accelerators in a outer barrel plus inner rod arrangement, from between these the projectile is launched.
The ring projectile thanks to its shape has very little air resistance and excellent cutting power, letting it also rip through many kinds of armor. The guntends to generate a lot of heat and smoke after several shots though.
The loading mechanism, and maintenance is relatively simple so these are quite reliable weapons.
