I understand, but this is not exactly what I mean. In Iron Mode, you as a player still know where your units are, because you are controlling them. Of course, other units don't know about other friendly units they have no C2 contact with.
However, when a unit is spotted, the spotting unit immediately knows if this is a BLUFOR or REDFOR unit, even if the spotting unit does not know what role this unit has (infantry/anti tank/hq), the spotted unit is shown with a blue or red "?".
In my opinion, there should be a neutral spotting state where a target has not been positively identified as an enemy, but it is known that there IS a unit. Players would then need to check with their mates if friendly units are in there, to PID the enemy.
