A Jedi Sentinel or Sentry is a Jedi who stands between a guardian and a consular. (Description for those will be added below) The sentinels or sentries have a combination of  both disciplines and civilian expertise. These Jedi sentries are unlike Jedi Knights or Jedi Guardians who travel from place to place, but can stay in one place for years at a time. If a sentry is assigned as a Jedi Watchmen, they will stay on that planet until death. Sentries usually carry a lightsaber, but unlike a Knight or a Guardian, the lightsaber's blade is commonly yellow. Not many people see Sentries, so not many people have a Yellow Lightsaber. Mainly because a Sentinel would rather have a peaceful transaction than a violent one. A Sentinel does not always wear the clothing of a Jedi, but the clothing of a local. (Some Knights or padawans get  yellow lightsaber, the color is a sign of a protector) some sentinels have gotten close to people they were asked to protect and married or fell in love.

       A Jedi Knight And Masters are an individual who who will commit to a life of solitude. The knight is the protector of the Republic and report back to the Jedi High council when a mission is complete. Jedi Knights are known for their fighting and amazing swordsmanship. The knights of the Republic carry a Lightsaber, the trademark of any Jedi.   The Knights lightsabers are commonly Blue, Orange, Green and Purple. (Purple is also not a well known lightsaber color, they purple Kyber crystals are only found in one place in the Galaxy)

     A Jedi Consular, They are the negotiators of the Jedi order, they are highly involved in politic and serve at the pleasure of the senate.  (Their lightsaber colors are the same at the Knights.)

      A Jedi Seer, a Jedi seer is someone who devotes their life to that of someone who will study the force and all its aspects. they view events from a remote distance. (During the clone wars, many of the Seers were killed in attacks on the Temples off the home world of the Republic)

     A Jedi Healer, A healer connects with the force to help them heal others around them. This was first seen when Obi-Wan Kenobi was a child and he healed many slaves, (Before Qui_Gon Jinn took him as a Padawan), This was later seen in the Jedi temple on Coruscant  with Master Yoda and many other Jedi.

    A Jedi Researcher, A Jedi who dedicates their life to studying all aspects of the galaxy, animals, foods, planets, things that can be used by Knights and Sentries. Jedi  Researchers almost never leave the temple, so often a  researcher is someone who has bean blinded (Like Talh, Master Jinn's friend) or like Master Taria Damson (Who had a terminal sickness, she was a lightsaber fighting teacher for senior Padawans)

      A Jedi Ambassador, Jedi Ambassador is someone who is a part of the senate and is under the Jedi Representative. They are the Jedi who speak on the behalf of the Jedi order during senate meetings (These Ambassadors were taken out of the senate after the battle of Naboo, Master Jinn and Padawan Kenobi were the last of the Ambassadors to do any bidding by the senate.

      A Jedi Representative, they are the leaders of the Ambassadors and decide what Master or Knight will take on what mission. The Jedi Representative was removed from power after the battle of Naboo, by the supreme chancellor. The Jedi Representative was still acknowledged as a leader but had no say in what the Jedi Order was asked to do. (A well know Representative is master Obi-Wan Kenobi)

       A Jedi Diplomat, A diplomat is someone like a Jedi Representative or a Jedi Ambassador but they do now hold any symbolism. Their job is much like the Representative or the Ambassador, they are a part of the galactic Government.

      A Jedi Keeper, the keeper is someone who does research for the Jedi archives. their job, much like that of a Jedi Researcher, is to gather information of the galaxy and store it on Holocrons and store it in the Jedi archives.

      A  Jedi Slicer, A tech specialist, a Jedi who is tech savvy. They can work with ships and hlolocrons. They are more tech savvy than the normal Jedi who take lesions in Computers. (One of the well Known Slicers was Obi-Wan Kenobi or Ben Kenobi)

      A Jedi Tech Expert, Someone who builds and programs droids for the Jedi Order. These individuals are smarted than the Tech Slicer, and can build almost anything. (One of the most well known Tech Experts was Anakin Skywalker)

       A Jedi Shadow, Like Jedi Sentinels they are stationary. they commonly are found on Korriban, the home planet of the sith. the Shadow's job is to root out any trace of the dark side. The Jedi Shadows are highly respected and take on only the strongest of Padawans.

     A Jedi Security Expert, someone who can disable any security system in minutes. These talented Jedi are taken with Master and Knights when they are going on a mission that requires breaking in. Some Knights double in this talent and are able to break in without the help of a security expert. (One of the well know user of this talent is Qui-Gon Jinn)
