Good luck Hosehead, great to hear your app is on it's way! As always: send Chief Gus my regards. Since your not a broken down old man like some of us you probably have a decent shot. I imagine they'd take a 4yr. prior Navy over a 2 yr. prior Army anyday
I'd love to give you a solid answer on how long it will take but it seems every one's different. Example: First time around I waited two weeks and found out I got my med-waiver: big yay! Two weeks later I found out I has passed pro-review board: bigger yay! And then I went before Aviation board and a week later I found out I was done DOH!
This time around all they sent down was a post card for the most part, or I think it might only have been a Fax or e-mail(?) simply telling them to pull my app' on file and re-review with the new ASTB test scores on file at P-cola. I already had my med-review/waiver and pro-review so it all went straight to the Aviation board and it's been a week and a half already??? We'll see.
I recall people on the forum saying their med review came last and have heard of others getting hired by their community first, but then having to wait on the other boards to be official. It seems to me there's no concrete way an app. gets reviewed so it's impossible to guess how long. I'm guessing it depends on the app itself, how busy the office is, how backed up are the different boards and such. I've heard no longer than a month on avg. and that jibes with what a few people have said here; providing you don't have anything extraneous to get reviewed, like WAIVERS!!!
Best of luck!
