It is hard to say. When this photo was taken, he may have been assigned to the 101st. Without knowledge of his duty assignment history, you can't tell from this picture.
Also, I don't know if they still do this or not, but when I was in we had regimental affiliations. I was in an infantry unit but was affiliated with Signal Corps. It may be that way with Division affiliation too, but I don't know.
