Possibly, but not necessarily, and most likely not. Each unit in each State must be given a specific mission, specific orders, when activated. There is no general muster for all the states as one would think with a branch of the armed services, even with a so called national emergency.

The NG is paid not out of the federal military budget, not in the same way as active duty (IIRC) when the Feds request them. Also, they do basically go to the Governor and request them.

I do know whomever activates them pays for them, whether it is fed or state.
