the problem with that is the Gov can only draw on her own state’s resources - so she is drawing personnel from existing civilian HCW staff who incidentally happen to also be weekendwarriors.
Remember just recently when they talked about how the unvaccinated are overrun in the hospitals and causing the healthcare workers to get burned out? So now you have taken civilian healthcare workers and made them via the national guard work extra shifts to cover for the civilian workers you fired, leading to even quicker for an hour and likely mistakes that can result in serious injury or death
