As for "Gefechtsverband Andres", I do not recognize it. I suspect that this is merely an unofficial term. This is possibly related to:

ANDRES, Werner.

This fellow seems to have been high ranking enough to be in charge of a temporary grouping of units.

The above does not really answer your question but it may help.
