[Roman]

I tried the option cover on stage 001. I moved two hexes German troops and then pulsed the key cover. Meanwhile Poles kept the head down with mortars and machine-gun fire. The Poles detected one or two sections at long range. And only when they were spotted the other 4 hexagons.
More then the test will progress without using the key cover to see how far I detected. Although progress will be cautious, only two hexes per turn.
Scenario 3 should also be interesting to investigate the option cover.
