ANBU Black Ops

The ANBU (暗部; "ANBU Black Ops"; Literally meaning "Dark Side"), short for Ansatsu Senjutsu Tokushu Butai (暗殺戦術特殊部隊; Literally meaning "Special Assassination and Tactical Squad") are an elite squad of shinobi hand-picked by the Kage, from whom they take orders.

They protect the village from exceptional threats, conduct high-risk missions into enemy territory, and deal with extremely strong ninja. They are also responsible for carrying out assassinations, tracking, surveillance, and missions requiring specially trained ninja.
