I just wanted to add a couple of things.
My Dad landed at Omaha in Sept 1944 with wools, the M-41 jacket and a helmet with the net. I have the pictures and uniform. He was in a combat engineer group(and it WAS a group) that later linked up with the 84th Railspliters. Now, if you go to their reenactment site, they don't allow M-41 jackets or helmet nets. Sure, the 84th may not have had them at first but I can assure you that some of the replacements or reassigned men did!
It's hard to believe that these ideas can happen when so many vets are still around to correct it. Of course, I have said before that the average soldier only saw his world around his foxhole
Just an observation that the soldiers of a unit may have been all alike until they stepped on the boat to go overseas. Then it all changes.
