Agree with moobob that they've flooded the MOS. But that shouldn't discourage you. That's the intel MOS at the forefront right now, hence the need for more. Analytical jobs can suck, but I've been very, very lucky (or was when I was still doing the work).
Find some folks in the MOS and ask them about their job, but don't tell them you're interested in being one - or they may throw a recruiting pitch at you. You're already "in the game," so your curiousity would be natural. Just ask questions and listen.
I found when we were runing several HCTs out of our TOC in OIF that it took some to gain their trust - I got answers at first because of my position/rank, but once I gained their trust, I got real answers. They're very insular.
