I'll second Super Galaxy’s remark to Kikuchiyo, thanks for the excellent info! It's comforting to know others are in the same boat. I'm trying to fill a Non-Vol. position our unit has been tasked to fill, but have been told no due my established DOS of 2 Aug 2012 (3 year point). I'm one of those unfortunate overmanned mobility guys (hollow paper air force; most of our dudes are tasked on extended TDY's). Kikuchiyo, do you have any insight if they can extend tours past the four year point? If so how long? Could it be matched up with the Non-Vol. tour we have been tasked? Thanks for your time!
