We can call them “Molly Pitchers”.
What you did there............I SEE IT.........
Molly Pitcher’s primary mission was to carry water for the crews. She took over for her husband when he fell out (he survived). Molly would have sponged the piece & rammed down the charge & ball, but I doubt she aimed & fired it. The gunner was in charge of firing.
Anyway....I don’t know about women Marines in combat MOSs. Just don’t.
