So my question is how many soldiers would the US Army need to recruit during twilight?

I am guessing initially Guardsmen and USAR, and recalled members would used to fill critical positions need to deploy regular army divisions. While some new personnel with key cadre members would

A. Roundout National Guard/USAR Units
B. Establish new units

Other newly recruited personnel would thrown into the replacement system and assigned to existing units

am I out to lunch
