Interesting topic for a small campaign
 

Some new documents from 1968 (as well as witnesses) have surfaced: Commander of 2nd Motor Rifle Division upon the news of Soviet invasion personally visited all division's garrisons plus few others and aletrted their commanders. They were to prepare for hostilities and evacuation under fire. Evacuation vectors - towards Western Germany.
Once I have some time left, will think about it. Would be perfect use of my border mountains map set :) Also fighting retreat with hordes of refugees in the way might get... interesting ;)
