I just came across this forum. My father served in Co. K of the 473rd. He was originally in the 900th AA/AAW Battalion. He died in 1990, but I have all of his service medals. He was awarded the CIB and the Bronze Star, as General Marshall recommended.
If you want more info about the 473rd, there is a combat history that is very good. I have a copy, but I would also recommend Patrick Audinet's website devoted to the 473rd. (

Neat site.
