If you dig a little on this site, I think in 2013 or 2014 someone posted what the board typically looks for and it doesn't seem like its really changed any. There was a post on here as well (cant remember the year) but it states the type of leadership and quals they look for. I want to say they lean more on FCPO and Chiefs and then go down the line. They also like to see AMDO's writing LOR's and obviously the higher they are, the better. Like HornetMO12 wrote about him mentoring someone being selected, I was mentored by an AMDO as well and was selected. If you have not been to the amdo.org website, its pretty helpful when it comes to the directory. The AMDO community typically knows what they look for but it will vary.
