The disk near his collar is an enlisted infantry branch insignia (crossed rifles), indicating he was an infantryman.
On his chest, the badge on top is the Combat Infantryman's Badge (CIB). It is hard to be certain with the ribbons because of a lack of color, but the top ribbon I believe to be a Purple Heart Medal. The three ribbons below may be the WWII Victory Medal, Good Conduct Medal and European, African, Middle Eastern Theater Service Medal. I think they may not be in the correct order of precedence.
In case you do not know, Anthony John Diglio 31330587 appears to have been an infantryman who served in combat during WWII, hence his CIB. He was seriously wounded by artillery fragments in Jan 1945, based on a NARA Medical care/ hospital admissions card. He would have received a Purple Heart for these wounds sustained in combat.
He was also likely (retroactively) eligible for a Bronze Star Medal based on his CIB.
