A six year old Pentagon document on Recruiting and Retention (also available here), written before the Global War on Terror, reflects a reality more pronounced today:
Fewer Americans have military experience than ever before. With a smaller force serving at fewer bases, there are increasingly fewer Americans who have direct experience with our military. Fewer people know someone who serves–or has served–in uniform. The transition from the draft to an all-volunteer force in the early 1970s also decreased broad military experience, knowledge, and understanding. Today, fewer elected officials, journalists, teachers, business owners, and employers have experienced military service.
Has this disengagement allowed a more expeditionary attitude and how much has it contributed to the use of private military companies?
