Setting up hostages

Hello fellow ArmA devs. I am a fairly new dev and I am working on a mission that is a dual hostage rescue and sabotage mission. I'm running into an issue with the hostage rescue part. I found a good tutorial on how to place an AI and make him a hostage and able to be "rescued". In my scenario I would like the BLUFOR AI hostages to join my team after being freed so that we can bring them back to base. Also, since they are going to be surrounded by REDFOR, what is the best way to make sure the REDFOR AI do not smoke them.

Thanks for any help or suggestions.
