Strassen-Bau battallion

[Der Kuenstler]

Three more questions - in Stalingrad the info window looks like this:



In other hexes it says rubble 50% - what does this figure mean? I read already that rubble has no effect on combat so what is the percentage for?

Also, in some stacks the figure for the number of men in the haxe is followed by an X like this:



What does that mean?

And thirdly, some of the hexes in the city show more than 1300 men in them. One hex has 1584, one has 1314. The parameter data says 1300 man limit. I don't get how this can be?
