Military Leadership Diversity Commission Decision Paper #1: Outreach and Recruiting [open pdf - 2MB]
"Unlike most other organizations, the military operates as a closed personnel system; senior leaders are not brought in from the outside but are instead brought up through the lower ranks. As a result, the demographic composition of servicemembers at accession directly influences the demographic composition of future senior leaders. Therefore, a necessary first step toward improving the demographic diversity of senior leaders within the military is to attract and recruit a demographically diverse population of qualified candidates from which future leaders can be drawn."
