This statement isn't true...I've seen often times...being in the Army for 16 years..that DA..Department of the Army, Assignments Section, based on the Army NEEDS, especially because of his/her rank...that they do not have to request a recruiting assignment, simply will become DA select..meaning, a top percent reguardless of MOS, will get selected for a TDA..Temporary Duty Assignment.
Having over 10 years in, and then you re-enlist, which will put you over the hump mark, you will simply re-enlist for the "NEEDS OF THE ARMY"..
