C-rank (Earth-2356)

C-rank is one of the six types of classifications in the galaxy. It is preceded by D-rank and followed by B-rank. It was typically used when classifying Force techniques intended for Jedi  of the Jedi Knight level. C-rank techniques are often one of the first techniques a Jedi will learn that require some amount of training.

There are also C-rank missions. Within the Jedi Order, these missions were usually assigned to Jedi Knights, or in some cases, Padawans. Assignments include bodyguard duty and hunting wild animals, all of which will likely pose some risk to the person hired, albeit, according to Jango Fett there generally shouldn't be a chance of combat against other bounty hunters on these missions. A notable example of a C-rank mission was Team Obi-Wan's assignment to escort Tazuna to the Outer Rim planet Wavna. After it was discovered that Tazuna had assassins and bounty hunters after him the mission was stated by Obi-Wan Kenobi to have turned to B-rank or even A-rank depending on threat level. C-rank missions pay between 30,000 and 100,000 creds.
