The United States Department of Defense ( DOD or DoD ) is the federal department charged with coordination and supervising all agencies and functions of the government relating directly to national security and the military. The DOD is headquartered at the Pentagon in Arlington, Virginia. The Military Departments at the Pentagon publishes some of the very best manuals, handbooks and guidebooks on a wide range of topics; teaching skills, tactics and techniques.
