When Golda Meir was PM of Israel, she visited America and met with the Moetzes Gedolai Hatorah, at the time consisting of Rav Yaakov Kaminetzky ZTL and Rav Moshe Feinstein ZTL.
She said, I understand why the Rabbonim are opposed to women serving in the army, but why are you opposed to the Sheut Leumi, having the young women provide service to the country. Rav Moshe was going to answer when he was interrupted by Rav Yaakov who said I am older I will answer. He then proceeded to say that the kedusha of am yisroel is based on the father knowing where his daughter is and having control where she is and what she is doing till he walks her down to the chupa. Sherut Leumi takes that control away.
