Hi and thanks for the information you gave me already.
It's good to be back too.
As for my friend's Engineer unit ..... no idea.
He trained stateside with the 185th Engineer Combat Battalion, but then there is a gap.
He was sent to the 981st after he got wounded in France and stayed with the till he got the order that he was to be transferred to 26th Division where he became a BAR gunner.
I have his original transfer order from 981st Eng. Maint. Co. to 26th Division dated 15.12.1944.
And documents from his training with the 185th Eng. Combat Bn stateside.
The 42nd did have occupational duty; inactivated: 29 June 1946 in Europe.
Jim went home in April 1945.
I'll write him and ask if he really can't remember or if he can find a document with his unit mentioned in it. He's on the road a lot with his RV, enjoying retirement to the fullest. 
Thanks again and I look forward to any other piece of information. 
Erwin
