I think they're meant to represent the attempts to build the fortified lines after the failing of citadel, otherwise known as the Panther-Wotan lines

They much like the Hindenburg fortifications were to be constructed behind the lines and then fallen back onto. STVAK had other ideas and overran the limited fortifications in the south.

Thanks. Yes, I understand that they represent those lines. My question was do they represent engineering efforts to build the defenses or combat units to man the defenses? If they are combat units, then where in the historical OOB do they fit?
