ok so how strong are the anbu really, and how can u become one, i remember the anbu getting defeated so easily and being very stupid eventho they are supposed to be like one of the secret ninja forces in the village, and wat class are anbus?? they dont seem to be as strong as some jounins but at least as powerful as a chuunin, they seem a bit overated tho, esp when the tsunade, went like this is only a normal class mission, not an anbu one, to the new leader guy.
