Just to let you know I don't sleep (yet)...
Today finished everything below the railroad to Hungary. Plus some fields (off screen to the left = South). Plus, for orientation purposes, used beach sand to draw the current border line.
On this screenshot, you may see positions of several bunkers - squares are heavy objects (though some of them are "old" - built in 1935 before the forts were typised, on initiative of commander of forces in Slovakia - the "old" objects were armed just with machineguns, some were really bristling with them, but in 1937 they were reworked to better fit into typised patterns, meaning usually limiting armament and filling up some loopholes with concrete to increase protection) and white circle is one of three vz.37A type light objects (exception to the rule, while standard weapon of vz.37 objects was vz.26 LMG, in Petrzalka bridgehead all three objects built had two HMG's).
AARGH! Forgot to add a link to pic!
