Army Boot Camp

Grandpa Razo is in the middle of the gang. He is the darkest and only hispanic in the picture. I'm not sure which camp this is in California. The picture may have been taken around the late 30's or early 40's. My Grandpa entered the Nattional Guard late 30's and became enlisted to the regurlar Army in 1941. Not sure if this is the training when he entered the National Guard or when he entered basic training for the regurlar Army. If anyone knows any other details about where this might have been or know any of the guys in this picture. I would love to know any history regarding this picture.
