Battlestar Galactica Autocannons and Machineguns
Autocannon, machinegun, or firearm technology has advanced little in the last few centuries. From a cost standpoint, the technology is effective as hell. The weapons use a chemical propellant to fire projectiles at a high rate. The shells or rounds can be solid or, if large enough, explosive. Solid slugs rely on velocity and impact to rip through a target; explosive rounds detonate on impact.
Auto-cannon weaponry is primarily point-and-shoot, relying on the coordinated convergence of ammunition at a point in front of the vehicle and the experience of the pilot or gunner (using a computer aided aim-locking system) to bring down an enemy target. Glowing tracer ordinance also aids a pilot or gunner in guiding shots to the target.
