That should present no problem whasoever Greg. We have often attached Jager detachments of 4 models to Prussian brigades in later parts of the war. They act as independent units requiring single unit actions. The ignore support/supporting rules. You should be fine with that. I think I may even have examples under the Prussian section in the book.. can;t remember

I certainly put something in for thr Sambre Crossing scenarios in WI a couple of years back
