if i was to be shot in the back of the head and survive would this \/ be likely to happen?

okay if i was about 19 years old and in the army and i got shot in the back of the head with an AK47 in a long range engagement with the enemy surrounding me. would i just freeze in my spot for a while and then eventually collapse? would it affect my nervous system in such a way that i could only move my fingers for yes and no at first and then gradually build up the movements of my mouth so i can talk again. it's for a book i'm writing and i havent studied neurology before so any help is much appreciated. thanks
