SSgt -
I'm on recruiting now, but it's Marine recruiting, so I don't think my advice would apply directly (you guys do things a little differently than we do).
I will say this - if you want to get a specific geopraphic area for your assignment, my recommendation is to just take some leave, and go to that Battalion HQ, and talk to the SgtMaj there. Let them know you've already got orders, and that you want to work for them. Try to have a couple of "good" reasons why, but it shouldn't matter. HQ's are always looking for fresh meat - volunteers always help.
You know what they say about volunteering, right?
