He can try logging into DoDMETS, the civilian contractor used by DoDMERB to coordinate with applicants and contract providers. If DoDMERB has received his file from USAFA, then he might be able to log into DoDMETS (different login than DoDMERB) using the new user guidance. If he can get in, he should create a profile, change his password, and he should see forms and information.
Go back to the DoDMERB TRICARE site. Go back to the Contacts section in the left-hand menu, scroll down past the names, and read the info at the bottom about what happens when. The DoDMETS link is there. The regular timing and sequencing has been messed up due to the DoDMERB site outage, so why not test-drive logging into DoDMETS in advance of any email?
And bask in the pleasure of knowing a USAFAPS opportunity has been offered, and a seat on 2028 is likely waiting upon successful completion of all requirements.
