As a prior service 11B who is putting together paperwork to head to MEPS soon, do I have choices in duty stations? What should I expect?

Duty stations? No.

Expect to get offered a MOS based on the needs of the Army.

SPC (Join to see) There is the chance that you could be offered the incentive to choose a duty station. It all depends on what you are offered at MEPS.

Incentives for PS vary depending on your circumstances; what job you take, if you need retraining, if you are offered cash bonus, if you get a duty station choice. Unfortunately there is no way to know what is available until you go sit down at MEPS.

I don't know if this will answer your question. Are you keeping that MOS? Are you re classifying? In my situation When I changed from ARNG to Active Army I was offered re classify to a new MOS. I had to go back to a military installation to retrain a new MOS, Right after the training I had the opportunity to chose from various duty station openings that were available. Good Luck
