Imperial Navy commando

The Imperial Navy commandos were specially trained sentinel troopers that fought for the Galactic Empire.

Overview
Navy commandos were lightly armored soldiers that were trained for patrol, guard and monitor duty. They were typically stationed at key Imperial facilities where they provided accurate covering fire for other units. Squads consisted of five to seven commandos and a sergeant, and sometimes an officer or a medic.

Naval commandos wore roughly the same uniform as the Stormtroopers, though elements of the design were similar to that of the Scout troopers: their black body suit partially revealed and little leg armor shared the resemblance to the Scout troopers' own outfit. The Navy Commandos appeared to have temperature-controlled chestplates similar to that of Snowtroopers on their backplates, making them among the Empire's environmentally-specialized divisions of troopers. The helmets had wider visors than those of the Stormtrooper variant, similar to that of the Scout trooper, with comlink antennas attached to the right side of the helmet.

Arsenal
Depending on their rank, mission, profile, and training protocol, an Imperial Navy commando primarily wielded the E-11 blaster rifle which was the standard armament issued for many Imperial troops. However, some Navy commando sergeants carried laser-guided sniper rifles that were deadlier than the average weapon. Other commandos did not wield their rifles for the majority of their assignments; instead, these select troops manned blaster turrets stationed around the battleground.

Though they did not use them often in battle, Navy commandos also carried thermal detonators as part of their equipment.

Gear
Most Navy commando helmets were equipped with comlink antennae. Squad sergeants often wore orange shoulder pauldrons and multipurpose backpacks as well as their specialized helmets. Each commando was issued a small black ammunition pouch that was worn near the left shoulder; this pouch stored extra ammo for their blasters.

History
Numerous Naval commandos were present on the Imperial shipyards over Nar Shaddaa where they fought against members of Rahm Kota's militia. Those defending commandos were also killed by Galen Marek in order to maintain his secrecy as Darth Vader's apprentice. Later, the Empire stationed garrisons of Navy commandos on Coruscant at the Jedi Temple to prevent prying eyes from investigating the ruins; three entire garrisons were mowed down at the Temple by an unknown assailant, with most of the armored bodies sporting lightsaber gashes. Other garrisons were placed on Nar Shaddaa, Raxus Prime, and Felucia, where they were employed to patrol Imperial stations or cities.
