Kage bodyguard. It may have said he was on kakashi's level but does anyone think he could even give kakashi a reasonable fight? Kabuto was too afraid to raise a finger to hebi sasuke after he took down orochimaru and kakashi fought fearlessly against ms sasuke.
He obviously has them but he is an underdeveloped character because he has such little screen time. He also would rather finish a fight quickly. Would you knife fight people if you walked around with a machine gun?
