William - I found reference to both the 630 and 607 TD BN on the web Go to your browser and type in the name of the 630 tank destroyer. On the panser (don't ask why that name) site you will find info about the 630th. They were with the 28th Infantry Division. That is the Division that marched through Paris after the Liberation. They did not stop- they simply marched in wonderful formation through the city and on to battle. A picture of that march is on a US stamp. One of the battles they were in is the Hurtgen Forest battle.There is an excellet book about the 28 D called "Follow Me and Die: the Destrution of an American Division in WWII" by Cecil Currey. Out of print. I think. Ask your library.
The other the 607th has a web site. Just type in the name and explore. Mary
