Sith Trooper

Sith Troopers, also known as Sith Soldiers or colloquially as "Red Army Soldiers" due to the red-coloured armour of some Sith troopers, were the main infantry units of the Second Reborn Sith Empire's armed forces. Troopers were distinguished by their shiny red or silver armour and a specially-designed mask with a reflective gold or copper visor. Troopers typically had no connection to the force, unlike their warrior counterparts, Sith Knights. But there had been cases where some troops tested positive for force-sensitivity, cutting them off from Trooper training programmes and enrolling them in Sith academies where they would train to become Sith Lords.

The majority of troopers were either human or partially human, due to the humanocentrism in the Sith Empire. As aliens were treated like second-class citizens and had less rights than humans and weren't allowed to enroll in the Sith Military."'The Sith Army is the strongest!' -SRSE Trooper Slogan"

History
Majority of Sith troopers were civilian volunteers who chose to enlist in the Sith Military, some had also defected from other factions and also joined the Sith military as these troopers also had previous military experience. Those who wished to enlist and had no prior military experience were sent to military academies or training camps on worlds such as Dromund Kaas or Taris. However, the weak were siphoned out through the merciless Sith training schemes, resulting in an efficient and powerful fighting force. The fear present in each trooper not only spurred them on in battle, but also prevented them from turning traitor for a second time.

Some Sith troopers used the fear they instilled in people and the influence they gained from the suit for their own gain, threatening people and intimidating citizens into giving them what they wanted. Others, however, saw themselves as simply doing their job, or believed that the Sith would be better at ruling the galaxy.

Sith troopers were typically assigned to military units which was either under the command of another fellow trooper who was a commanding officer, an admiral, or a General, who was also a Sith Lord. As a trooper was assigned to their units, they were also assigned to stay on a world as their current deployment, the world of deployment was decided by a commanding officer. Most troopers of a military unit were assigned on one world, where some had to stay on two worlds for partial time.

Armour
The standard armour for Sith troopers were silver or red-coloured plating and black under-armour padding alongside a mask that covered the wearer's entire face and had a gold or copper visor with it. The material of the armour plating was made of beskar and cortosis, with the red armour variant being more durable than the silver variant. Red or Silver armour did not indicate any ranks. Although Elite troopers wore obsidian-coloured armour and Commandos wore scarlet-red armour with a special-designed mask.
