Re: Anbu sucks
Anbu Black Ops are very important to the Leaf Village, the Anbu Black Ops are like the Navy Seals/Secret Service/CIA of the Narutoverse.
So they do things behind the scenes for the welfare of the village.
Ex:Assassination Missions,Scouting,Recon,Intelligence Gathering,Counter-Intelligence, Interrogation,Counter-Terrorism,Clandestine Missions,etc.
So thats what they are used for, Top Secret missions.
Why do you think they keep a Bingo Book of top Priority targets with many details of their abilities, obviously for Intelligence gathering and future Assassination missions and for breaching other villages undetected and gather information on other villages and enemies.
They do Scouting and Recon because they are stealthy and fast and secretive and slip under the radar just like Kakashi,Itachi, and Sai does.
They are there to prevent spies and missing-nin from stealing and leaking information about the village to other villages(Counter-Intelligence).
After they capture a spy in the village or near the village they interrogate them as seen from Ibiki interrogating people alongside Anbu and Inoichi.
They attack terrorist such as Pein when they breach the village with powerful jutsu as seen Anbu fighting the summoning pein.
You never see Anbu fighting in the frontlines because that would defeat the purpose of being secretive,stealthy, and tactical.
Kakashi, Itachi, and Sai could do all the above thats why they are in the Anbu.
Yamato is in there because he has a special skill(Mokuton),and if you payed attention you may have seen an Inuzuka,Hyuuga,and Aburame in the Anbu Root because they have unique abilities such as Yamato
