I think how the platoon leader should control his platoon, is by playing like a real time strategy game, he gives way points and objectives to squad leaders, then the squad leaders decide how to carry out those objectives. This, mind you would only work if everyone was working together, or else you would have a squad being stupid and not following orders, so maybe an xp boost to normal actions if a squad member is killing people/capturing near a platoon leader set objective. This could be awesome if done correctly, and i trust the developers to do it correctly.
