Dad managed to get himself assigned to the advance unit of the 709th Combat Military Police that would be going in with the lead Invasion Forces.
The rest of the 709th would not go over for more than a month after the Invasion and would be in the lead assult on Paris.

The 709th ecountered German resistance and snipers that had to subdued before they could secure the City of Light. They were The Law in Paris.

I had heard that he'd turned down a battlefield commission and asked him about it, wondering why he didn't want to be an officer. He made light of it and said he'd wanted to stay with his men.
My Mother corrected him, saying to me, "He turned it down twice. "

That meant that two officers were casualties. Officers were prime sniper targets. It also meant that he had a better chance of keeping his guys alive as their sergeant.
