Still, the service branches are always shuffling the deck to maintain the appropriate mix of senior and junior service members, especially in the more technical fields (such as psyops). This could represent an uptick in the use of psyops capabilities and the need for additional senior NCO's, or it could reflect a crop of senior NCO's that are retiring and need to be replaced. Sometimes a field can become bottom heavy, thus they reduce the points necessary for promotion (yes they use a point system), and when a field is top heavy they will offer early retirement, re-classing, and other options.
