    On December 13, 1637, regiments of what would become the United States National Guard were assembled in the Massachusetts Bay Colony. 
    The National Guard is a reserve component of the U.S. military. Most members of the National Guard serve part-time, with the traditional service requirement being “one weekend a month, two weeks a year.” Some members, such as pilots, serve more often. National Guard troops are often called up to serve as disaster response teams during floods, tornadoes, or hurricanes. 
    The first “national guard” were militias from different communities in the Massachusetts Bay Colony. Colony leaders assembled the groups to strengthen their defenses against the indigenous Pequot people.
