Unit A unit was a standard formation of soldiers in the Sith military that fought under the leadership of the Brotherhood of Darkness , during the final phase of the New Sith Wars . Size and role . A typical unit seems to have been a relatively small - scale formation of infantry , which could sometimes be described as a company . The exact number of men in a unit is unclear , and may not have been standardized : the term " company " is used elsewhere for forces ranging from a few dozen soldiers to more than two hundred . The most that can be said for certain is that one specific unit , the Gloom Walkers , appears to have numbered something more than a dozen troopers . In most armies , forces of this size would have been subdivisions of larger formations like battalions or regiments , but in the Sith military , the only larger formation mentioned specifically is the division , and units , such as the Gloom Walkers , were independent groups of troops that were treated as the basic components of the army . New recruits were assigned directly to specific units , and although transfer was possible , it seems to have been usual for veterans to remain with the same formation . A force of a thousand units was deployed in the assault on Kashyyyk , reinforced to nearly two thousand in order to defeat the Republic defenders there . From here , twenty units were sent to pursue the retreating garrison to Trandosha , where they fought in the Battle of Hsskhor . It is possible that some units were equipped with transports or armor , but for the most part , they appear to have been infantry deployed from orbit , probably in landing craft supplied temporarily by naval forces , comparable to the line infantry of the Imperial Army a thousand years later . Some sense of the relative balance of forces within the Sith military may be gauged by the composition of a group of reinforcements that arrived on Ruusan during the campaign : two divisions of infantry and a " core " of snipers , but just a half - platoon of repulsorlift armored vehicles . Internal organization . While comparable in some respects to an infantry company , the unit seems to have had a simpler command structure , similar to a platoon , with a Lieutenant in command and a single Sergeant . There was also a position of Senior Trooper , but it is not clear if this was a single third - in - command position , or a more widely - used rank . A " communications officer " is also mentioned as being attached to the Gloom Walkers during the Battle of Phaseera , but his exact position in the unit is not known . Ordinary soldiers were known as Sith trooper s . Units could be split into squads , but these seem to have been temporary divisions of the command into tactical teams , made as required for an individual mission , rather than permanent component sub - units . Weaponry and equipment . Most troopers in a unit were armed simply with the TC - 22 semi - repeating blaster rifle , the basic armalite of the Sith forces , with just two power - packs . Veterans and NCOs could request more advanced weaponry , and would also carry sidearms like the GSI - 21D disruptor pistol , while marksmen — of which the Gloom Walkers had four — were issued with TC - 17 sniper rifles rather than the standard TC - 22 . The Sergeant and at least some of the other personnel in the unit had short - range comlinks , but the main comm unit of the Gloom Walkers seems to have been large enough that it remained at their base camp on Phaseera , and may only have been issued due to their deployment on a flanking maneuver . Other special equipment , such as interference boxes , could be used , but was probably only issued for specific missions . The low number of power - packs issued to the average Sith trooper , with just a hundred shots in total , may explain the widespread use of edged weapons during the Seventh Battle of Ruusan .
