EDS trooper armor

Environmental Defense Security trooper armor&mdash;formally known as Thranta-class trooper armor and referred to as EDS armor&mdash;was a specialized suit of armor designed specifically for use of clone troopers to protect against hostile environments, most notably areas with high concentration of poison or a lack of oxygen.

Due to it's extensive features and prototype armor material, EDS armor was hard to acquire and produce in large amounts, and was therefore reserved to specialized units with the Grand Army of the Republic who would make frequent use of it. Havoc Company, a unit within the 30th Assault Legion, was known to use EDS armor almost exclusively.
