• The Army celebrates its birthday on June 14
  • The U.S. Army is now the largest branch of the military
  • Below are some fast facts about the U.S. Army

It's time to celebrate a rather special birthday. On June 14, we celebrate the 246th anniversary of the creation of the U.S. Army.

The U.S. Army was formed by the Continental Congress with mostly volunteer soldiers and amateur troops to fight the British in 1775. It wasn't quite as strong as the Army we know today, but the soldiers had the will and passion to defend their land. From those humble beginnings, the U.S. Army has now become the largest branch of the U.S. military.
