The K.A.T. use laser weapons as an alternative to plasma. It there travles though the univers, they have come across several races that are uneffected by plasma, so it has become standered practice for all troups to have a laser pistol as a side arm. What laser weapons lack in damage, they make up in ammo, and flexability.

Lasers are about the most common weapon, as well as the easiest to modify. This became apparent when the K.A.T. fought a group of aliens that possessed a great deal of understanding of lasers, and their creation. With this groups destruction, the K.A.T. took their knowlege of energy weapons, and adopted their use of the Laser Energy Sword.
