How many militia are in the National Guard?

Answer 1

Technically, one could say that all the National Guard are militia, in accordance with the Militia Act of 1903, which classes the National Guard as the Organized Militia, or one could argue that none of the National Guard fit the Constitutional definition of a militia, as they wear the uniform of the Army, and on the basis that the Total Force Policy ultimately maintains that the Regular Army, Army Reserve, and Army National Guard are one force.

Whatever your stance on this matter is, all National Guard personnel are required to attend the same Basic Training and Advanced Individual Training which their counterparts in the Regular Army, Army Reserve, Air Force, and Air Force Reserve are required to attend.

Some states have an auxiliary branch, known as State Guard Forces, State Defence Forces, etc. While administered under the National Guard bureau of each state, these outfits are not actually members of the National Guard.
