The Sith war droid Mark II was utilized by the Sith Empire during the Great Galactic War. The Sith deployed these droids during the Sacking of Coruscant, first during the invasion of the Jedi Temple, and later during the occupation of the planet. These droids had three "feet" and four arm-mounted blasters.
Shortly after the Sacking of Coruscant, Jedi Master Orgus Din encountered two of these droids in the city's underlevels. The two droids were destroyed shortly after by Republic Special Forces Lieutenant Harron Tavus.
