Mishler's revised edition of a game originally published in 1973 by SDC's in Conflict Magazine #4. A solitaire variant is included.'NORAD is a representation of a hypothetical nuclear war between the United States and the Soviet Union in 1962 . . . In 1977 the Mishler Company purchased the rights for NORAD. Only minor changes were made on the game board and the unit counters. However, several changes were made in the rules, and the solitaire game was completely re-done and the 'Assigned Targets' optional rule was added. The historical simulation aspect was improved by giving the American player the capability to hide the exact location of his/her fighters. Also, the Russian bombers may no longer fly endlessly back and forth across the game board. In addition, several rules and the number of units was changed to balance the game.' - BoardGameGeek
