For those who haven't seen this video, below I have attached a link that will provide some information in regards to the board process directly from PERS-8. The recording was dated a month before FY19 E7 selection board process but has relevant information. The video outlines what the board looks for, how adverse information may dictate the selection process, LTBs, and additional information in regards to the selection process. Good luck to all of you!
