>if they draft me I'll use my guns
They will have enough armed draft officers to keep coming for you until you are dead or surrender, and then you will be hanged.
>I will go to prison instead
That is something from the past of a civilized white society, they will beat you and drill you into an obedient automaton and will march you from battle to battle until you are dead
>I'll frag my officers
They aren't going to give you opportunities to do that, you will only get ammunition when combat begins and they have left the combat zone.
This has been the reality of war and conscription since written history began. Once you are drafted you are property of the state with no rights and are dead. If you manage to survive the war you will come home and drink yourself to death or commit suicide.
