ANBU Naruto Shippuden Temporary TattooManufacturer: GE AnimationThe ANBU ( , literally Dark Side, Viz manga Black Ops, English TV ANBU Black Ops ) is actually short for Ansatsu Senjutsu Tokushu Butai ( , literally 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 shoulder (Men: left shoulder. Women: right shoulder) a Ninjat strapped on their back. They know the layout of the human body in detail, and have developed several techniques to perform their duties, such as paralyzing the target. ANBU are considered the elite, and they perform high-ranked and dangerous missions. Within the ANBU of Kirigakure, and presumably other ninja villages there exists a sub-group called Hunter-nin ( , Oinin, literally Chasing Ninja, English TV Tracker Ninja ), given the specific duty of hunting down rogue ninja, and destroying their bodies, so their village's secrets won't be revealed to foreign ninja.
