Yes, Marc. In the early days of the American Army it was organized as combined arms legions. This didn't last more than a few years before it was replaced. During the Seven-Years period there were some units that were sort of combined arms, but it was more typical to see them style themselves that way but in practice be light infantry.

And Tom, I tend to feel that the ACR in either its more current or (preferably) its Vietnam TOE would be outstanding for this type of warfare.
