No - It is basic Steel Panthers.
If private Snuffy spots something then
everyone on the battlefield knows exactly what Snuffy knows. Even if he has no radio, and is miles outside of shouting distance. Just like you the Player-God can select Snuffy and see exactly what ammo etc he has.
So the paras spotted the helo with thier Mk1 eyeballs, and a SAM on the other side of the battlefield now knows this by "SP telepathy", and is in LOS = Fox One!.
One could write complicated rules about who knows what, with individual spot lists for each and every unit, and spotting results getting passed up and dowwn the chain of command. Nasty horrible code, and not worth doing since you, the all-seeing Player God
KNOW that Pte Snuffy saw a panther there, so you the god-palyer can plot "blind" artillery even though your arty spotter unit
really has no actual knowledge of that panther's existence. Or you the Player-god now know there are tanks on your flank, and so you pivot your flank company to face the oncoming troops (who really should continue on clueless and get surprised). There is no way to legislate for this in a 2 player "total command" type game where you have total access to your pieces.
So tabletop gamers ignore such, or they play "command HQ" type games with each player in his own room, and umpires in a third with the real map. Umpires put units on player maps and they can lie!
. That is the way the Prussians did Kriegspiel - military types like it, civvie rivet-counting micro-manager types usually
hate that sort of game where they dont get to move around their own units with their own hands, and the umpires keep the rule books and roll the dice
.
