The Pentagon, headquarters of the U.S. Department of Defense

The Department of Defense (DoD, USDOD, or DOD) 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. The Department is the largest employer in the world, with nearly 1.3 million active duty servicemen and women as of 2016. Adding to its employees are over 801,000 National Guardsmen and Reservists from the four services, and over 740,000 civilians bringing the total to over 2.8 million employees. It is headquartered at the Pentagon in Arlington, Virginia, just outside of Washington, D.C.

The Department of Defense is headed by the Secretary of Defense, a cabinet-level head who reports directly to the President of the United States. Beneath the Department of Defense are three subordinate military departments:

In addition, four national intelligence services are subordinate to the Department of Defense:

June 25, 1950 1126 - 2126 East Coast Time

Early on the evening of Saturday, 24 June 1950,* press news flashes first informed Washington that the Communists had broken the peace in Korea.
 
At 2126 (9:26 PM) [2126+1400=3526-2400=1126] hours the State Department received the first official word from Sŏul. A telegram from Ambassador Muccio stated that the North Koreans had apparently launched an all-out attack against the Republic of Korea. The State Department promptly relayed this information to the Defense Depart-ment, to President Harry S. truman at Independence, Missouri, and to United Nations Secretary General trygve Lie at his residence in Forest Hills, Long Island.#71
 
The report from Korea sounded like a major violation of the United Nations charter's ban on military aggression to Secretary General trygve Lie, and he informed the State Department that he was prepared to bring the Security Council together to consider the matter. Before making a formal recommendation to the Security Council, however, Lie preferred to obtain a report from the United Nations Commission on Korea.
 
 
*There is a time difference of fourteen hours between Korea and Washington. For example, 0400 hours, Sunday, in Korea is the same time as 1400 hours, Saturday, in Washington. The times and dates used are those of the place where the events described occurred.
