I have 3 US army officer cap badges that are uncertain for me.

Two are ’standard’ design, but 2"x2" with screw post and a pin at the top. Are these US Army Female Officer cap badges from WW2 era/ Korea or are they pre-ww2 officer cap badges?

The badge without the shield of stars - is it a National Guard badge? Again, it is 2"x2" and has English-style attachment lugs??!

Thanks for suggestions,
