The military budget is that portion of the discretionary United States federal budget that is allocated to the Department of Defense, or more broadly, the portion of the budget that goes to any military-related expenditures. This military budget pays the salaries, training, and health care of uniformed and civilian personnel, maintains arms, equipment and facilities, funds operations, and develops and buys new equipment. The budget funds all branches of the U.S. military: the Army, Navy, Air Force, Marine Corps and Coast Guard.
