I often run historical games in an RPG format, with all the players on one side and the others run by umpire(s). It is a very simple way to implement hidden movement and also enforce a proper command structure.
Id be a bit hesitant to make them roll dice to do things though, a "team" of players is quite chaotic enough. In Science VS Pluck, the players have "characteristics" (e.g. Quick to anger) which let's the players ham it up a bit and play in character.
