I have a picture of my dad with a garrison hat pin that I'm trying to identify. Unfortunately the site picture limitation does not allow me to post the picture. It I believe was taken at Camp Upton where he entered as a selectee during WWII. I believe this because the uniform does not contain combat badge, ribbons, etc.....that are on another picture that I have. The pin appears to be the shape of a shield with a bright "Y" that spans the entire shield. Can anyone point me in a good direction for identifying the pin.
