Storm Commandos
this was a group of Imperial soldiers trained to speciallize in guerilla warfare. They were generally referred to as Shadowtroopers, and were initially trained by Crix Madine. Despite the fact that Madine himself defected to the Alliance, the Empire maintained the Storm Commandos because of the niche they filled in the overall Imperial war machine. Storm Commandos were distinguished by their black armor, which was modeled after that of a standard scout trooper. Up to forty Storm Commandos worked as a single unit, divided into four groups per team: standard commandos; assault troops trained for vehicle combat and artillery; soldiers who were experts at sabotage, demolitions and stealth; and a tech team devoted to keeping gear functioning or jury-rigging makeshift supplies.
