Does the national guard work with the army national guard?

Answer 1

yes

There are actually 2 types of national guards. There is the Air National Guard which is part of the Air Force and the Army National Guard which is part of the Army. Then there is the State Guard which certain states have and work closely with the army national guard.

Answer 2

The state National Guard and the United States National Guard are one in the same, with the only variances being the authority they were activated under (state or federal). Not all National Guard personnel are Army National Guard - there's also the Air National Guard, which falls under the Air Force.

Now if you're referring to the State Guard (or State Defence Force), that is a different organisation, administered under the same authority as that which administers the National Guard for that specific state. The State Guard (which is not present in all states), is an entirely state run outfit, and is not federally recognised.
