The Imperial Military
The finely tuned Imperial war machine is as diverse as the myriad of planets that inhabit Sith territories. This diversity, however, is tempered by the uniformity and discipline bestowed unto them by the indomitable will of the true Sith galactic Emperor, and his many top-rate war academies and training regimen programs located on nearly every world, in every sector, even the furthest reaches of space; at various space stations and facilities.
To be a member of the Imperial military is to be a being of excellence; disciplined, skilled, and prepared.
The full ranking system utilized by the military can be found here. Also take note that although the various branches of the Imperial military are made up predominantly by those not attuned to the Force; it is nonetheless possible for Force Users -- and actual Sith practitioners themselves -- to be members of the military. They are almost always of the rank of Captain or above, and are known with the honorific "Lord" prior to their rank, such as 'Lord Captain' or 'Lord Marshal'.
