Katarn Mark VI armor (Galactic Civil War)
From Wookieepedia, the Star Wars wiki.
Katarn Mark VI armor was a variant of Katarn armor used during the Galactic Civil War.
It bore some resemblance to the 501st Legion markings. It was the only variant of Katarn armor that was still in use by the Imperial Military. However, it appeared that it wasn't common for the Stormtrooper Corps to receive any sets. Instead, operatives tended to gain them.
