Of the thousands of military officers on active duty, only those who have served in Washington, D.C., since 1961 have had the opportunity for direct involvement in the Department of Defense (DOD) Planning, Programming, and Budgeting System (PPBS), And of these only a relatively few have become intimately associated with all aspects of the multifaceted system that manages DOD's resources, Today PPBS serves as the raison d'etre justifying the bulk of the military billets in the Washington D.C., area.
