An interesting fact about the U.S. Army is that 24 presidents were members of the U.S. Army or various state militias. Additionally, President George Washington is the one who chose the colors of the Army uniform. Various other colors were tested over the past two hundred years.
The U.S. Army is older than the United States itself. The Continental Army was led by Major General George Washington during the Revolutionary War, before the United States won its freedom and became its own established country. The Continental Army has since become the U.S. Army.
The Army was the last branch of the U.S. Military to adopt an official song. The song, "The Army Goes Rolling Along," was officially adopted on Veteran's Day 1956.
Members of the U.S. Army have been deployed to 135 countries out of 195 in the world. They operate under nine key principles that include foreign internal defense, unconventional warfare, counter-insurgency, direct action and information operations. The remaining principles are counter terrorism, special reconnaissance, counter proliferation of weapons of mass destruction, and security force assistance.
Some astronauts are members of the U.S. Army and are given special recognition for their accomplishments. Special recognition badges include the Congressional Space Medal of Honor, the Master Space Operations Badge and the NASA Distinguished Service Medal.
