Which agency is known as the Department of Defense in the U.S. government?

The Department of Defense (DOD) is the primary agency responsible for coordinating and supervising all agencies and functions of the government related to national security and military affairs. This includes overseeing the Armed Forces and ensuring that military strategies are developed and implemented effectively. The DOD is crucial for national defense, international security, and the military’s role in various operations, both domestic and abroad. Its central role distinguishes it clearly from other agencies that focus on intelligence gathering (like the CIA), domestic law enforcement (like the FBI), or signals intelligence (like the NSA). Understanding the specific responsibilities and functions of the DOD is essential in recognizing its pivotal role in the U.S. government’s defense strategy.
