What kind of information are you looking for?
Like I said in your other posting, I'm a 14J AIT Instructor, so theres a good chance you'll be in one of my classes.
EDIT: You're pretty close as far as stateside duties go. Its a lot of maintenence and training.
When you're deployed, you could serve in a number of different jobs, just depending on what unit your assigned to. It could range from paperwork to working on a weapon system that prevents rockets and mortars from hitting the FOB. Its really too many possibilities to list as far as jobs go.
14J itself is a lot of technical work. You will learn how to operate several different computer systems, as well as how to integrate other systems. You will be a much broader range other than just detecting aircraft.
It has a good transfer into the civilian world if you're not looking to make a career of the Army. Raytheon and Boeing like to hire former 14Js.
As far as AIT goes, be ready to take a lot of notes. You will be getting a lot of information thrown at you in a fairly short time frame. Just pay attention and do your best. We will take care of the rest.
Duty stations - Anywhere. 14Js are a very versatile MOS. You can be assigned anywhere from Division level down. You won't have much say in where you end up, but just know you can go anywhere.
