Naruto Mission Ranks
These are some of the types of missions that a typical Ninja would complete in their daily routine.
S-Rank missions are the highest paid missions a ninja can go on. They are extremely dangerous and are usually only assigned to a select few highly skilled ninja.
These missions are completed by Jounin rank ninjas and usually include important tasks that will greatly benefit the hidden village or country, such as assassinations of wanted criminals and escorting important people across dangerous territory.
B-Rank missions are mostly completed by Chuunin rank ninjas. They usually involve assignments such as reconnaissance missions and assassinations of low ranking enemy ninja.
These are completed mostly by Chuunins, but are sometimes done by Genins as well. Various assignments include, hunting wild animals for food, and acting as a bodyguard for important villagers.
This is the lowest class mission that can be completed and are usually done by Genins. These missions are usually small priority and involve completing small errands for people around the village.
