The militia of the United States, as defined by the U.S. Congress, has changed over time, complicating its meaning.
During colonial America, all able-bodied men of certain ages were eligible for the militia. Individual towns formed local independent militias for their own defense. The year before the US Constitution was ratified, The Federalist Papers detailed the founders' vision of the militia. The new Constitution empowered Congress to regulate this national military force, leaving significant control in the hands of each state government.
-------------------------
Today, as defined by the Militia Act of 1903, the term "militia" is primarily used to describe two groups within the United States:
Organized militia – consisting of State militia forces; notably, the National Guard and Naval Militia.[9] (Note: the National Guard is not to be confused with the National Guard of the United States.)
Unorganized militia – composing the Reserve Militia: every able-bodied man of at least 17 and under 45 years of age, not a member of the National Guard or Naval Militia.

The militia is the people. Guns were needed on the frontier for defense and to provide food.
