Army question......................…

I want to be in the national guard and i will proabably join when I finish my Masters degree in October of this year, my question is that i want to concentrate on the imagery yst section of the army national guard my long term goal would be to work for the NGA, or NSA. Do imagery ysists typically work here in the states or do they deploy often, i dont mind to deploy but it will give my family a better understanding of where my work is going to be done, thanks for any help?
