Whoa Marion!
You provided me with the first solid evidence when you gave me the link to the 101st Calvary. Found the reference to the 2756th on the SAAR River and read from there. But sure enough, dad's unit was there. Considering that this was in Feb 44, I'm reasonably comfortable that he was too. I also recall him mentioning the Saar River at one time. He also mentioned Bavaria and the history you provided goes on to talk about that part of the world. Thank you so much! 
I would have never thought to search the site you did. Obviously your years of experience gives you ideas of where to look. I've Googled 2756th ECS but did not run across this link. I guess I should have added more detail to the search. Is this site part of Florida State (FSU)?
Contact the Corps of Engineers! So obvious that I might have thought of that.... Eventually. 
I like their price too.
Yep, let's see what the VA provides and then see where we stand. What you gave me will keep me going for a while.
I appreciate this SO much.
