On December 13, 1636, the Massachusetts Bay Colony organized three militia regiments to defend the colony against the Pequot Indians. This organization is recognized today as the founding of the United States National Guard. From the article:
"The History and Roles of the National Guard
The Army National Guard is an elite group of warriors who dedicate a portion of their time to serving their nation. Each state has its own Guard, as required by the Constitution; in fact, it is the only branch of the military whose existence is actually required by the Constitution.
The Army National Guard began on December 13, 1636, when the Massachusetts Bay Colony organized three militia regiments to defend against the growing threat of the Pequot Indians. Today, the Army National Guard continues its historic mission of providing defense for the nation.
Since 1636, the Guard has brought glory and honor upon itself and its soldiers through quiet and selfless service. Do you think you have what it takes to be a member of this select group?
In the Guard you become a Soldier. What does it mean to be a Soldier? It's being a part of noble tradition of service extending back almost 400 years. It means you become a member of the best trained, best equipped, and most respected military force in history. It means you will make a difference."
