Input: Context: Robert Tralles Herres ( December 1 , 1932 -- July 24 , 2008 ) was the first Vice Chairman of the Joint Chiefs of Staff ., The Chief of the National Guard Bureau (CNGB) is the head of the National Guard Bureau, which is a joint activity of the Department of Defense, and since 2012 is a member of the Joint Chiefs of Staff. The Chief of the National Guard Bureau is the highest-ranking officer in the National Guard of the United States; which is a joint reserve component of the United States Army and the United States Air Force. The CNGB serves as the principal advisor to the Secretary of Defense, through the Chairman of the Joint Chiefs of Staff, on matters involving non-federalized National Guard forces and on other matters as determined by the Secretary of Defense. The CNGB also serves as the principal adviser to the Secretary of the Army, Secretary of the Air Force, the Chief of Staff of the Army, and the Chief of Staff of the Air Force, on matters relating to federalized forces of the National Guard of the United States and its subcomponents; the Army National Guard of the United States, and the Air National Guard of the United States., The Joint Chiefs of Staff (JCS) is a body of senior uniformed leaders in the United States Department of Defense who advise the President of the United States, the Secretary of Defense, the Homeland Security Council and the National Security Council on military matters. The composition of the Joint Chiefs of Staff is defined by statute and consists of the "Chairman of the Joint Chiefs of Staff" ("CJCS"), "Vice Chairman of the Joint Chiefs of Staff" ("VCJCS"), and the Military Service Chiefs from the Army, Marine Corps, Navy, Air Force, and the Chief of the National Guard Bureau, all appointed by the President following Senate confirmation. Each of the individual Military Service Chiefs, outside of their Joint Chiefs of Staff obligations, works directly for the Secretary of the Military Department concerned, i.e., Secretary of the Army, Secretary of the Navy, and the Secretary of the Air Force., The Vice Chairman of the Joint Chiefs of Staff (VJCS) is, by U.S. law, the second highest-ranking military officer in the United States Armed Forces ranking just below the Chairman of the Joint Chiefs of Staff. The Vice Chairman outranks all respective heads of each service branch, with the exception of the Chairman, but does not have operational command authority over their service branches. The GoldwaterNichols Act of 1986 created the position of VJCS to assist the Chairman in exercising his duties. In the absence of the Chairman, the Vice Chairman presides over the meetings of the Joint Chiefs of Staff and all other duties prescribed under and may also perform other duties that the President, the Chairman, or the Secretary of Defense prescribes., The United States Armed Forces are the federal armed forces of the United States. They consist of the Army, Marine Corps, Navy, Air Force, and Coast Guard. The President of the United States is the military's overall head, and helps form military policy with the U.S. Department of Defense (DoD), a federal executive department, acting as the principal organ by which military policy is carried out.
From the time of its inception, the military played a decisive role in the history of the United States. A sense of national unity and identity was forged as a result of victory in the First Barbary War and the Second Barbary War. Even so, the Founders were suspicious of a permanent military force. It played an important role in the American Civil War, where leading generals on both sides were picked from members of the United States military. Not until the outbreak of World War II did a large standing army become officially established. The National Security Act of 1947, adopted following World War II and during the Cold War's onset, created the modern U.S. military framework; the Act merged previously Cabinet-level Department of War and the Department of the Navy into the National Military Establishment (renamed the Department of Defense in 1949), headed by the Secretary of Defense; and created the Department of the Air Force and National Security Council., Subject: robert t. herres, Relation: military_branch, Options: (A) air force (B) army (C) navy (D) united states air force (E) united states army
