I think the following 'team' command and control scheme is easily doable (no matter what the nay-saying-fanbois-may-say).
When sectioning off a team, they can be given orders 'normally'. That is, as many as the game actually allows.
Once away from the Squad Leader, they can only be given further movement orders IF in C&C.
C&C means a voice/visual LOS to SL (or radio or wire commo).
An example would be:
A squad has panzershreck weapon. The squad teams off a AT element and orders it to move forward and occupy some woods near a road intersection. The rest of the squad (and SL) move around the woods to flank the road. Once both elements have completed their moves, they lose LOS with each other. The shreck may be given fire orders, covered arc orders and perhaps even small length crawl or hunt orders. But they may not be given run/quick/move. (I wish the game still had withdrawl but that was thrown out also). But the intent is that orders roll downhill and there are very little nodal command decisions. I would not necessarily think that the shreck would have delay to anything except hunt or crawl orders.
Now, since all of what I am suggesting is taking place during the orders phase (no one plays real time, I am sure of it), it is not the grand programming effort that the yahoos always imply. If it is, well...then something is wrong with the coders. And probably the code also.
One of the issues I see is that the 'orders' and 'SOP' are not evolved from CMx1 that much.
