What's the pin on him?

[ProudGrandDaughter]

My grandfather.  Staff Sgt George D. Jackson. 

WW II. Started out a medic, finished Infantry Staff Sgt.

His discharge papers are on my profile.

I am very new here and new to this, so please pardon my ignorance. I'm trying to learn and piece things together. 

He was in the 90th Division, Company E  359th Infantry. 

I have his medals. (Except the ones he's wearing in both attached pictures and the "ruptured duck") I'm attaching a picture of the medals to this post. His discharge papers/medals all match up. 

But there's a picture of him (also attached to this post) wearing wings? I think it's wings anyway. It's a photo he sent home. He wrote on the back of the picture.

Anyone have any ideas what that would be? He wasn't a pilot.
