weapon Help

I am a good builder and have created two things i need scripts for. (1) I need a script to launch missles from a stationary launcher (not attached to me), and have them home in on a commanded person, no push.(2) My second problem is with an automated turret. I need a script that will allow me to command the turret to fire and stop. I also need a tracking script to keep the turret aimed at the nearest person.I would like both of these objects to be command based. Please tell me if this is possible, and help if you can.

Here a script that might help your missle. Put this in the main part on the object. When object is rezz Click on the object. It well ask you if you would like to attech the animation. Hit Yes this well trun online. This well shoot the object/bullet or whatever. You just need add the missle or bullets name and sounds
