In some cases you may be allowed to determine your first duty station prior to signing your contract. I did. Well, actually, I was given three choices, and was allowed to pick the one I preferred. Talk to your recruiter. They work on quotas. If they don't sign up enough people they get in serious trouble. Just tell the recruiter "I want 11-B, I want Air Assault, and I want the 101st Airborne or else I'm not signing up!" and I can pretty much guarantee he'll make it happen.
Outstanding 30GRH!! Wicked has it right but it will also help if you do/did well on your ASVAB. Great choice, the 101st has a long and proud history of outstanding service to this nation. You won't regret the decision, but remember you'll be expected to represent the Screaming Eagles in ever aspect of your life.
