Magnaguards, sometimes referred to as Grevious' Magnaguards, were a special force of the Separtists. During the Clone Wars, the Magnaguards tested their skills on many Commando Squads. The Separtists were very proud of their project and they decided to appoint the Magnaguards as body guards to the Second in Command of their army, General Greivous. Due to this fact these droid were only manufactured for General Grevious. It was unknown how many of these Magnaguards Grevious had, but it was estimated to about twenty.
