A doubt about Engineers / Sappers

[Marc]

I'm working in some of our contents for our future website. Now I'm rewriting my adventures related to our Pre-Kalisz campaign while improving some things under the light of the experience of two groups that have played them. One of the things I'm trying to improve is plausibility.

So, I need some suggestion from anyone familiarized with the US Army. The group of characters are members of a newly formed "special sapper unit", and they, theoretically, were chosen from the units integrating the 5th Infantry Division. In the listed unis integrating the 5th ID appears the 7th Combat Engineer Battalion but it seems more specialized in heavy special purpose vehicles (CEV's, AVLB, etc.). I want the kind of combat engineers acting as infantry but trained in destruction of fortifications, breach opening, etc (the example of German engineers/paratroopers in Eben Emael comes to my mind). So, for my campaign background information, where can I find these men and women in the 5th ID? Will they be members of the 7th Combat Engineer Battalion or must I search them in some other place?

Mmmm... I hope I explained it well...In fact part of my problem is that I know that in Spanish, the terms Ingeniero (Engineer) and Zapador (Sapper) divide the two very different jobs of the same arm. I don't know if the same difference works in English but I've been unable to find a "Sapper Company" in the 5th ID.

Thanks in advance.
