I know there are former missile commanders here who will confirm that they and their deputy carry sidearms while on duty in the remote case that he/she refuses to obey authenticated orders.
Carried sidearms in the capsules for ten years. They are now gone as the security police convinced the higher ups we didn't need them.
The sidearms were for the protection of the Sealed Authenticators and not to shoot our crew partner. Why would we shoot them if they did not want to turn keys? They sure as heck couldn't turn them after we blew their brains out.
The way the missiles systems are set up more than one crew in a squadron could refuse to turn keys and the missiles would fly anyway.

That’d be funning you. Shooting the other guy would make no difference to being able to launch. They were for protection while visitors were present and not to shoot the other guy. Shooting the other guy was a War Games movie scene that was pure fantasy.
