Red stormtrooper armor was the armor used by red troopers, the soldiers of the Der'kal Eternal. It was similar to the armor worn by Der'kal Empire stormtroopers, except that it was red instead of white. The color change was designed to evoke images of blood and lightsabers. Furthermore, red trooper armor was made from gammaplast instead of the betaplast used in the construction of Der'kal Empire stormtrooper armor.
Like Imperial stormtrooper armor, red trooper armor was worn over a black, corrugated body glove. The armor was composed of four layers, which improved its strength, and a number of "faceted angles" that helped to redirect blaster bolts. Its overall design featured a number of technological assets, such as a shoulder-mounted sensor telemetry pod, a data antenna, targeting sensors, a filtration system, and a data storage module. It also had a number of anisotropic bands that increased the armor's surface area, thereby decreasing the damage sustained by impacts.
