I know that it changes every year, but does anyone know if there is a published list for The Class of 2012 (or 2011/any prior class really) of all the selection options?
While I do not have the Class of 2012's selection list, you can estimate what will be available. It depends on your branch. If, say, you are selected by the Infantry Branch your brigade and post options will look something like this (no particular order and not based on anything official):
1. Fort Bragg, 82nd, 3rd Brigade (Airborne)
2. Fort Campbell, 101st, 3rd Brigade (Air Assault)
3. Fort Stewart, 3rd ID, 4th Brigade (Mechanized)
4. Fort Hood, 1st CAV, 2nd Brigade (Mechanized)
5. Hawaii, 25th, 2nd Brigade (Light)
6. etc,etc
If you are not Infantry, but Armor, Artillery, Engineers, your choices will look similar. Less light assignments for the Armor, obviously. If you are aviation, you have to go to flight school.
