It was Kiev, I only roughed out the calculations.
As far as public domain goes, I had permission to give a lecture on the war plans and a fair amount of detail on the war SOP was included. I omitted any mention of Chapter 6 however as that was still classified.
Kiev was one of the targets I used to illustrate deep penetration at low level. The others were Lenningrad, Murmansk, the principal ones on the Baltic littoral, and then the rest spreading towards Big M.
I did not seek, nor was I granted, any clearance to discuss NEAF War Plans. They were just as exciting.
