DOUBLE-VIBROBLADE: The double vibroblade was basically two vibroblades attached to a central, twisted hilt. It was a weapon that was difficult to master, but deadly once fully trained with it. It was similar in name and design to the ancient vibro double-blade except that it did not have the cortosis-weave enhancements. This DOUBLE-VIBROBLADE had cortosis-weave enhancements all throughout it's handle.

[Indepth explination of a single VIBROBLADE] Vibroblades were a type of bladed melee vibroweapon that used ultrasonic vibrations to increase cutting effectiveness. A vibroblade resembled a short sword with a high-tech look and feel and consisted of the same basic design as other vibroweapons: the weapon's hilt or handle usually contained a compact ultrasonic vibration generator, causing the blade to vibrate at an incredible speed, making even the slightest glancing blow become a gaping wound. Vibroblades were dangerous to use against electrical weapons, as they conducted electricity. Electrocution, however, would be the wielder's last concern. Traveling up the length of the blade, the electricity would connect with a vibroblade's energy cell and ultrasonic vibration generator. The result would be a miniature explosion with enough force to take off a hand.

A vibroblade could be fitted with cortosis-weave, allowing it to parry the blows of lightsabers and energy swords. The cortosis-weave became less common when the probability of fighting a lightsaber-wielding opponent decreased. By the time of the Galactic Civil War, knowledge of the cortosis-weave had faded, and the cortosis mineral itself had become exceedingly rare. A highly adaptable variant of the vibroblade, the prototype vibroblade, could be fitted with a number of weapon enhancements.

Equipment and training were lavished upon them at the Imperial Royal Guard Academy on Yinchorr. Classes consisted of forty students per course who attended a brutal training regime. Usually, by the end, there were only a handful of candidates left to become Guardsmen and it was not uncommon for there to be only a single survivor. Students would train fencing and fighting in an arena called the Squall. Classes consisted of approximately forty students each, and trainees were partnered up into doubles. During a yearlong training program, recruits sparred against each other continuously to perfect their combat skills. A step away from the squad-based stormtrooper training received on Carida, by working both alone and in pairs, recruits learned how to rely on themselves or on a teammate to achieve victory. Training mainly centered on Echani hand-to-hand combat, and failure often resulted in death. Casualty rates were very high; out of Kir Kanos's class of forty-two, only two reached full Guardsman status—all others were killed in training. During their final test, trainees fought each other to the death before Palpatine himself. Only a handful would survive this final test in a display of their loyalty and skill.

During training, the Guardsmen were inculcated with the belief that Palpatine, and his every order, were beyond fault or question.
