Sith Juggernauts were Sith Warriors who fought for the Sith Empire during the Great Galactic War and the Cold War that followed it circa 3653 BBY.[1]
These Sith specialized in combat endurance and were known for wearing armor that provided them special protection in battle. Sith Juggernauts were known to primarily wield one lightsaber in combat, and were frequently adept at using the Force to cause terror and despair in enemy combatants.
