The rule of two (Starwars x high school dxd)

Tree of sith command

Sith Lord: This is the leader of the Sith faction and the one who calls all the shots, it is also the responsibility of a Sith Lord to train one apprentice in order to inherit the title and command of the faction. They are frequently in the high satan class of power, and sometimes reach the heavenly class.

Sith Lord (Apprentice): As the main apprentice to the Sith Lord, this Sith is automatically promoted to Lord and is second in command of the faction. The apprentice will inherit the title if their master dies, but can take the title if they become powerful enough and kill their master in lightsaber combat. They range from high ultimate class to high satan class in power.

Sith General: Sith Generals are the physical leaders of large portions of the Sith military. They have a lot of power over their section of Sith forces and train multiple apprentices at once in order to further their abilities quickly. A Sith General will be the most likely chosen by a Sith Lord to become their new apprentice once they reach a certain level of power or they show unusual potential. Sith Generals range from low to high ultimate class in power.

Sith Commander: Sith Commanders are the apprentices of Sith Generals and their hands in the military. They are the ones that will lead sections of an attack force on any given battle field. Usually a Sith General with be present giving orders, but in the case that they aren't or they die, the most powerful Commander will take command. Much like Sith Lords, Sith Commanders will be promoted to General if they kill their master in lightsaber combat. Though that have more competition to get stronger first. They range from low high class to low ultimate class in power.

Sith Captains: All a Sith Captain is, is a equivalent to A Commander, just for the Air Forces, since the Sith faction is the first supernatural faction to use air ships in battle. They range from low high class to low ultimate class in power.

Sith Master: A Sith Master is not for the military, their job is to train new recruits who enter the Sith academy. They use harsh and brutal methods of training in order for their students to become true Sith. They range in the high class level of power.

Sith Assassin: Sith Assassins are used for covert or undercover missions. They pride themselves on their extreme efficiency to get any job done. They are one of the three graduate classes out of the Sith academy. They range in the high middle class to mid high class in power.

Sith Sorcerer: Sith Sorcerers focus solely on their abilities in the force, and are the only class of Sith that typically choose not to wield a lightsaber. Their role in the Sith are long range soldiers in battle and give guidance to their Sith peers. They are the second of the three graduate classes out of the Sith academy. They range in the high middle class to mid high class in power.

Sith Warrior: Sith Warriors are the grunts when it comes force-users in the Sith military. They aren't particularly of high skill in any one category but are more than enough in all of them to be formidable in combat. They are the final class of the three graduate classes of the Sith academy. Most Sith in existence are Sith Warriors. The greatest of the Sith Warriors is given the title of "Sith Juggernaut" due to their overwhelming strength and ability to strike fear into their enemies. They range in the middle class of power, and sometimes low to mid high class.

Sith Crusader: Sith Crusaders are the name used for Sith apprentices that are in the Sith academy. They are proficient in the fundamentals of force usage and lightsaber combat, and are starting to move on the advanced teachings if their master deems them ready. By this time, they are starting to gain an understanding of their mission and role in the Sith empire, and have a similar mind set of most Sith, along with their negative emotions and lust for power and blood. Sith Crusaders pick their path as a Sith with choices as Warriors, Sorcerers, or Assassins depending on their skill sets. They range in the high low class to low middle class in power.

Sith Acolyte: Sith Acolytes are not Sith quite yet. This name is only used as a formality as they are looked down upon by most real Sith. They are known as "dark humans" by mostly Crusaders and at this point, and are merely force-sensitive. Acolytes are taken from their homes and families when they are discovered to be force-sensitive by a Sith Master and have to pass either one massive test, or a multitude of small ones depending on the Sith that found them. If they pass, they become true Sith and start their journey in the Sith academy as a Sith Crusader, and are subsequently rewarded with the task of getting Kyber for their very own lightsaber. They range in the low class of power.

Sith Troopers: Sith Troopers are foot soldiers of the Sith empire and are not force-sensitive. They are the ones who operate other Sith weapons powered by Kyber, such as blasters, cannons, tanks of all sorts, and speeders. They are the ground forces of the empire and are the non force-sensitive equivalent of Sith Warriors. They are trained much like normal human militaries, only much much harder. They range in the low class in power and status.

Sith Pilots: They are equal to Sith Troopers but for the air division of the empire. They are trained to pilot air fighters, interceptors, and bombers. They range in the low class in power and status.
