I would say your time depends on many things. What type of platform were you coming from? What type of leadership jobs did you hold? If you have a relatively common background - expect more time at the regional. If you have boxes checked like IP, director of ops, SEFE, safety officer etc then you might have a shorter stay. Bottom line - financially plan for 24 months and hope for 6. Communicate with the family that times will be lean for awhile relative to 20 year mil pay...tighten the belt now!
