About Your Military

The Department of Defense is an executive branch department of the federal government of the United States charged with coordinating and supervising all agencies and functions of the government concerned directly with national security and the United States Armed Forces.

Your military is an all-volunteer force that serves to protect our security and way of life, but service members are more than a fighting force. They are leaders, humanitarians and your fellow Americans.
