From horse's.......mouths (yeah, that's the word) who have sat on active and reserve promo boards (unknown re ANG), some universal truths...........
Almost a Letterman Top 10 list for advancement
1. Command
2. PME (in residence if at ALL possible, especially ACSC/equivalent and AWC/equivalent. Although it's been done and guys have done well without it, not going to school in residence is the first major roadsign that your career has just stalled. Recoverable, but you have to Avis it and try harder. Getting command is really hard without in-residence PME.)
3. Advanced degree
3a. Weapons School., etc, is way good.
4. High stratification in OPRs/PRF. "My #1 of XX" is your goal. If that, then a DP is a given.
5. Medal commensurate with your grade and one in there within the last 12-18 months. Combat decorations score better than "I was there" medals.
6. Deployment (s) documented in your records.
7. Records are up to date/nothing missing. Make sure all your OPRs/awards are in there.
8. And although I disagree with this one in particular, exec jobs are a fast track way to accomplish #s 2 & 4. Look at the GO bios and see how many of them did it. Like promotes like.
9. Get all the above done ASAP, then you don't have to worry about it at the last minute. WG/CCs and above don't really care that you are "enrolled" in ACSC at the time your board meets. They want to see it done.
10. Enjoy the ride; if being CSAF is not your be all and end all, then relax a little. Many, many before you have made Maj and even Lt Col and can look at themselves in the mirror just fine without pinging about most of the above.
For most promotion boards, each panel member takes about 15-30 SECONDS in the first cut to winnow out the dross or determine the top candidates The former go in the big "thanks for playing" pile and the second go in the "no brainer, promote now" pile.
The middle ground is where they will take a little more time to look at records.
