I understand Elmo you are only asking for a option toggle, I just don't see how it benefits FoW.
Personally, I'm for anything that reduces unrealistic levels of knowledge that no real commander would have. If that means getting rid of all screen representations of VP levels, I'm 100% for that. No real commander had such cheats, so if this game is to present as realistic a simulation as possible given the medium, why should we? These things only make it easier for the player to beat the AI, and they give online players advantages that real commanders simply didn't have, and that aren't necessary for play. These features only serve to encourage unrealistic play styles and turn what is supposed to be a simulation of realities of battle into a mere tactical game with a war theme.
Having never seen the game system I really can't comment on specifics, but if this game is to present a realistic simulation, it simply should have options that enable the player to play with only the level of detail that the actual participants had. The computer should be a tool for restricting knowledge and giving the player the same decisions that real commanders faced. Thus when a VP location is lost, players should not know that unless their soldiers can see the enemy take that location. Similarly, if a bridge is set to blow, the player trying to take the bridge should not know that there are explosives on it unless his troops can see them, and the player should have no idea of whether it has failed to blow until his troops are in a position to confirm that. Anything else is a cheat.
As for gauges of enemy strength loss - no commander should ever EVER know that. These kinds of things are simply cheats to allow players to more easily mould their strategy. Such flexibility was simply not available to real commanders, and thus such 'features' should NEVER be in what is marketed a realistic battle simulation.
