The Ball Gun was a popular moniker given to a portable, powerful weapon utilized by the Galactic Republic. This weapon was essentially a mobile, box-shaped artillery unit that could relocate and then set itself up for combat.
Upon arrival at its intended firing location, the armored shell of the ball gun would unfold, anchoring the weapon securely to the terrain and preventing any movement during operation. Once completely deployed, the firing mechanism would extend, showcasing a sizable, spherical aperture from which intensely powerful projectiles were launched. The name "ball gun" was derived from this spherical beam projector.
