Chiss Commando
From Wookieepedia, the Star Wars wiki.
Chiss Commandos were elite fighting troopers that first appeared during the Swarm War.
They were deployed on specialist tasks such as the placement of vape charges on selected locations. They wore camouflaged Fractal pattern armor, that allowed them to sneak across battlefields with ease, and used charric guns. They did not fear death and would sacrifice themselves if necessary. One notable engagement was a commando squad attempting to destroy a crashed Chiss vehicle.
