Sith Marauders were a variant class of the Sith Warriors, specially trained Dark Jedi exceptionally gifted in melee combat. Sith Marauders were fueled by hatred, rage, and cruelty; the Marauders would fill themselves with rage when entering a battle, entering a battle-fury fueled by the dark side. Thus, most Sith Marauders could duel any average Jedi, toe-to-toe, and win easily. Marauders cared little for the subtleties of manipulating others and lacked a deep understanding of the Force.

Sith Marauders reached their climax in strength during the time of Darth Traya, Darth Nihilus, and Darth Sion. Hidden in the Trayus Academy on Malachor, these warriors were trained in great numbers along with other Dark Jedi trained there. However, most of the Sith Marauders were wiped out, along with Sith Assassins and Masters after the Jedi Exile fought through the academy to confront Darth Traya.

During the New Sith Wars, the Brotherhood of Darkness trained Marauders in the Honoghr Academy, Gentes Academy, and Gamorr Academy.
