Good Conduct medal indicates he was prior enlisted for at least three years.

What uniform is this on? Pretty sure the Navy never had one with soft shoulder boards in navy blue.

Photo wouldn’t upload, but here’s the correct order:

Silver Star Ribbon Purple Heart Ribbon Navy Good Conduct Ribbon National Defense Service Medal Ribbon Vietnam Service Ribbon Armed Forces Reserve Ribbon Navy Reserve Ribbon Republic Of Vietnam Campaign Ribbon

It’s a little weird for him to be a supply officer (shoulder boards) and have a Seal pin. Lower two rows are out of order. Seal pins started in 1970, but he has one from his relatively short stint (only an LTJG).
