National Commission on the Future of the Army: Report to the President and the Congress of the United States, January 28, 2016 [open pdf - 14MB]
From "What We Found": "America's Army is the strongest in the world. It is made so by the extraordinary women and men who answer the call to duty and voluntarily choose to serve the nation when, frankly, they have many other opportunities. Sustaining the quality of the All-Volunteer Force must remain a national priority; the alternatives--accepting a less well-educated, less fit (morally or physically), or less-motivated force, or returning to short-term compulsory service--will not yield the Army America needs now or in the future."
