So, when I press Shift+O to see the anti air strength values I can indirectly see enemy units everywhere on the map, regardless of recon levels. I can for example use this to spot units at sea, or see where the enemy fort lines in Italy are, or just as cheap and dirty recon of general location of enemy forces etc. All without using a single aerial recon aircraft. Seems this function is a bit OP

Also, when I hover the mouse over an enemy unit in order to attack it, the pop up box shows the exact enemy estimated defensive CV, regardless of recon level.
