What is the defense weapon for a mongoose?

The primary defence of a mongoose is it's ability to fluff up its' fur so if a snake strikes, it only gets a mouthful of fur, and also its' super fast reflexes. Snakes and other reptiles make up a large proportion of it's diet along with other small mammals and insects.

Some say its' reflexes are up to 4 times faster than a house fly.

Its' teeth and claws are primarily for attacking it's prey and used occassionally in some territorial fights and courtship, otherwise they are used only in defence if handled or cornered.
