I'm active duty navy, a former P-3 pilot and currently a T-1 instructor. I'm going to get out at my PRD of June 09. I'm seriously considering going either AF part-time Guard/Reserve or Navy part-time reserve. How often do units open positions? Are the slots usually based on turn-over at the unit or are they budgeted per year? Can you apply if you are over a year out from your PRD? Do units usually want you to live geographically close?
