The 11 major force elements are subdivided into Program Elements. The program element is the basic building block of the FYDP. It is defined as “an integrated combination of men, equipment and facilities which together constitute an identifiable military capability of support activity.” It identifies the mission to be undertaken and the organizational entities to perform the mission. Elements may consist of forces, manpower, materiel, services, and/or associated costs. The PE consists of seven digits ending with a letter indicating appropriate service.
