Within the executive branch of the U.S. government, the Department of Defense (DOD) works directly to deal with national security threats and keep the president's military options open. For fiscal year 2005, the DOD has an estimated budget of nearly $402 billion. Of the total 2005 budget, the army receives $97.2 billion, the navy/Marine Corps gets $119.3 billion, and the air force gets $120.5 billion, with the remainder going to various other DOD departments. The DOD employs more than 3.3 million people, including an active-duty force of approximately 1.4 million and, in addition to weapons, maintains high-tech information systems and expertise the president and others can use to make informed decisions that lead to decisive actions.
