Skirmisher
this was the term used by the Old Republic's military officers to describe the small boarding craft used by the Separatist navies during the height of the Clone Wars. Skirmishers were usually cloaked, to avoid detection, and held back from the main fighting until most of the warships on both sides were engaged. Then, they would slip behind a Republic ship's defenses and latch onto the ship's hull, blowing a hole in the plating to allow swarms of battle droids to board the Republic ship. Because the Separatist boarding party was made up entirely of battle droids, skirmishers didn't require life support systems that could be detected by most scanners, providing an added meaure of stealth.
