I took a look at those decorations by blowing up the image with Irfanview until the resolution started to fail. I'm pretty sure that those silver wings are US Army, either pilot's wings or air crewman wings. They are the same in form and size except for the detail in the center of the shield of the badge.
The ribbons, in order of precedence are: Air Medal, Good Conduct Medal (an enlisted man's award); National Defense Service Medal, Vietnam Service Medal, Vietnamese Cross of Gallantry; Vietnam Campaign Medal.
The last two, bottom row on the right, the Cross of Gallantry and the Vietnam Campaign Medal are actually awards of the former South Vietnamese Government, and thus, like all foreign awards to US Servicemen, are at the bottom of the order of precedence. As the Good Conduct Medal is an enlisted man's decoration, It would be safe to bet that the wings above the ribbons are those of an air crewman.
"Hoo ahh" to our Widgeon pilot and his previous adventures and sacrafices on behalf of all of us.
