The first thing that came to mind to say to you is: YOU SHOULD BE SO PROUD. What a brave, independent, patriotic young woman you have raised. I know as a parent you must have reservations about her decision to do this and what the future holds for her, but she is being smart about this and is finishing her education with the distinction of being a ROTC student. She is making a name for herself and broadening her options for the future. You must be just beaming with pride ~ and you should be!
Please thank her for her service!
