- Co's have been upgrading min time ~18 months, but expect that to change now that there is not an AC void
- overseas assignments are 2 years if your single, 3 if you are married, normally with the option to extend a year for both. Stateside is 4 years
- Most guys from ETAR recently have done Dyess or Cannon for slick J's or AFSOC J's, some have gone to Little Rock as well. J model guys are high demand right now, but you have 3 to 4 years so things could change. With multiple squadrons standing up though it will probably remain similar.
Thats all I've got, I'll let someone who knows more about the other questions answer them.
