If you mean the eagle logo that marks the American intelligence agencies, then the prototype of this logo can be traced back to the American Revolution in 1782. George Washington, then general of the American Continental Army, sent a team of agents led by israel Putnam to collect information about the British army. The team used an eagle as their symbol to show their military honor and loyalty.

At the beginning of the 20th century, this eagle symbol was used in the US Army Intelligence Agency and later adopted by other intelligence agencies. Today, this eagle symbol has become one of the symbols of American national security system, representing the strength and responsibility of American intelligence agencies.
