When I was in GA:
About a total of 179 days at a time, with a return to the States for 4 months and then back to play in the sand. Combined total of about 537 days (1.47 years).
I soon left the military after that, was tired of going and with my career field full of ladies who always got pregnent right before their turn
so us men (about 230 out of the 460 (I guess half)) had almost immediant rotations.
