Academy Students:
The academy is where would-be ninja start; they are not actually considered ninja until they graduate. Academy students take formal and practical tests of all sorts and are taught basic ninja skills, such as martial arts, techniques, physical fitness and the way of the ninja. Basic weapon usage, such as kunai and shuriken, are commonly taught. Elementary ninja techniques, such as transformation jutsu and clone jutsu, though they vary from village to village, are also taught. Some villages also have an additional test given by the Jonin sensei of each three-man squad to see if they are truly ready to graduate, which determines whether the squad can work as a team.
Genin:
Genin are the lowest level of ninja. Because of this, skill levels vary drastically between Genin. Genin are put in four-man cells, consisting of three Genin and a Jonin sensei, in order to learn teamwork and experience true ninja life under the supervision and protection of an elite shinobi. The make-up of these teams is based on the individual skills of the Genin, so that there will remain a balance between the teams. When they become Genin, ninja start to do their bit for their village's economy, for which they are given a small payment. They are typically sent either on D-rank missions, which are the lowest rank and are almost entirely risk-free jobs of manual labor, or experienced genin are sent on C-rank missions, which are a cut above that and begin to verge on real "ninja" work, though they generally have a very low possibility of risk to the ninja involved.
Chuunin:
Chuunin are ninja who are qualified to watch over and guide other ninja. Chuunin have reached a level of maturity that primarily consists of leadership skills and tactical prowess. Some of them, like Iruka Umino, function as teachers and others, like Shikamaru Nara, serve as team leaders in charge of small teams who need to make decisions and utilize the skills of the shinobi under their command to the maximum effect. Upon reaching Chuunin level, ninja can wear an identifying tactical vest that holds ninjutsu scrolls. This vest is not required; instead, some look for more elaborate clothing like capes or robes. Chuunin are typically sent on C or B-rank missions.
Jounin:
Jounin are generally highly-experienced ninja with great individual skill who serve as military captains. They are often sent on A-rank missions, and experienced Jounin may even be sent on S-rank missions (which are considered to be the most difficult), and may carry out missions alone. They are sometimes assigned as sensei for three-person teams of Genin. Though it is as of yet unknown what one has to undergo to become a Jounin.
Kage:
Those who have achieved the title of Kage are the leaders of the five most powerful Hidden Villages and generally the most powerful ninja in their respective villages. The Kage stand equally with the rulers of their countries, oversee the activities of their villages, and are the leaders of ninja society. There may be exceptions, however, as a ninja may be the most powerful at the time of being installed as Kage, but may become less powerful upon aging, eventually being surpassed by a more youthful ninja. A Kage may retire and give the title to someone else; the title, once granted, is held permanently, creating a case where there are two Kage at the same time, with only one of them actually active. Their elite status is also attributed to the tendency for most Kage to have family members who were previous Kage, or be personally taught by a former Kage or student of a former Kage, or some combination of these factors. Most kage tend to be of an S-rank status.
S-rank:
S-class ninja have gained power far beyond an average Jonin and earned a legendary status. This title is merely a class rather than an actual rank; the ninja's official rank with a village will usually still be Jonin. However, it can sometimes be lower, or they can have no rank at all. The allegiances of these ninja range from being part of the village's own ninja to being wandering ninja who are still loyal to their village. Some ninja of this level tend to leave their villages behind to seek their own ambitions, thus becoming missing-nin. Ninja of this class are often noted in the Bingo book, a list of notable enemy ninja marked for assassination that each ninja village provides for its Jonin and ANBU squad members. Most ninja, even high-level ones, choose to flee rather than face someone of the S-class.
ANBU:
The ANBU is actually short for Ansatsu Senjutsu Tokushu Butai (Special Assassination and Tactical Squad), and is an organization of assassination squads that serves directly under the village's leader. The ANBU wear porcelain animal masks in order to distinguish themselves from normal shinobi and to conceal their identities, and also have standard uniforms consisting of black and gray armor, arm guards, a signature spiral tattoo on their left shoulder, and a Ninjatō strapped on their back (though certain ANBU wear black cowls over their uniforms). They know the layout of the human body in detail, and have developed several techniques to strengthen their job, such as paralyzing the target.
Medical nin:
Medical-nin are ninja who specialize in medical treatment and use medical-oriented jutsu to heal others. Becoming a medic-nin requires an extreme level of intelligence and excellent chakra control, since medic-nin use chakra to heal injuries. Aside from their medical training, their combat training consists mainly of taijutsu skills, with emphasis placed on evading enemy attacks, as the death of the medic-nin could result in the death of the team, though medical techniques can also be used offensively. On dangerous missions, a medic-nin will usually be sent along with the team, to increase the survival rate of that team.
Many positions are available but I will need proof of RP skills in the matter. I may also forward the RP sample to the guild leader and VC as well. If you are interested please don't hesitate to ask!
