Intel/analyst
Most of the National Intelligence agencies have vacancy positions listed on their sites, along with some guidance as to what you will require in the way of qualifications, citizenship etc.
In the meantime I would join some analytical organisations and see if there are courses available for basic analysis. Another tack is that many Universities and Colleges offer courses in either military or criminal analysis, both of which could be a starting point.
I would also start to familiarize myself with some basic Imagery analysis - plenty of sites to look at there and also do a course on i2 - Analyst notebook. these are all good starting points.
Hope this helps
