I don't have Fall of the Reich, but in both Torch and Overlord the 12-man US infantry squad is broken into a 7-man rifle squad and a 5-man BAR squad. So they need an order each, much like the rifle squads and MG squads in a German infantry platoon. There is no equivalent to the British Bren team rule.
That makes them harder to move, needing more orders, but less easily pinned.
