ANBU: "Ansatsu Senjutsu Tokushu Butai", meaning "Assassination Tactics Special Squad". (Dark side" or "Black Ops") It is a force of extremely talented shinobi of Chunin rank or higher who are chosen for assassinations, for village protection from exceptional threats, for conducting high-risk missions into enemy countries, and for dealing with extremely strong (S-Rank) ninja. They wear animal masks to distinguish themselves from normal shinobi, as well as to conceal their identities. The ANBU carry swords; this is somewhat unique in that Naruto, although it is a ninja manga, has very few swords. The ANBU is an organization that is under the direct command of the Kage. Hatake Kakashi was a former member and Uchiha Itachi became an ANBU captain at age 13. Morino Ibiki, the proctor of the first Chunin exam, is the head of the Konoha ANBU Torture and Interrogation Force
GenJutsu: Genjutsu ("Illusion Techniques") are techniques that use the chakra in the victim's nervous system to create illusions; an advanced intellectual Ninjutsu. Genjutsu techniques are notably easier to execute and counter for users of high intelligence, like Nara Shikamaru, good chakra controllers like Haruno Sakura, and Sharingan users like Uchiha Sasuke. The most commonly seen Genjutsu is simple creation of phantasms that cause the targeted person to hear, see, smell, taste and feel things that are not actually there in order to manipulate them; other applications of Genjutsu are rare.
