(hint, gojack this might be right up your alley!)
Here is another Accessions Brief, it goes into more detail, glossary etc.,

The numbers change every year, but if the idea is to get an understanding of the Accessions process, this one is worth muddling through.
But it's tweaked every year, so expect changes.
Basics as I understand it:
-Graduating/commissioning class is put on national OML (40%GPA, 45%leadership, 15%Physical)
-Everyone volunteering for AR or NG gets it.,
-top 20%(0r 10%?) on the OML are DMG's "Distinguished Military Graduate" they get their first branch choice.
-Army needs 'X' number of officers, after ed delays, NG, DMG, G2G, Nurse, SMC etc are taken out, a cut off line is drawn - on the OML - fall below the cutoff and you are mandatory NG/AR.
-The ones left between DMG and AD Cut Off - compete for assignments, and it's very complicated, you can extend service contract to get preferred assignment, grad school etc (horse trading) you list assignments by preference - lots of rules and fine print.
Notes:
The Active Duty Cutoff Line that sets the minimum scoring for active duty selection, varies every year depending on the needs of the Army.
Active Duty Cutoff Line is indicator of relative competitiveness to go AD,
previous yr = 68.5 and this yr = 71.5 means its getting tougher to go AD
Requests for ed delay are boarded separately (med, law school etc)
(and then go on the OML when they eventually graduate?)
hopefully some experts will chime in here, and correct my mistakes
