This is the PDF version of Korea: Race to Pusan
There are two files to print in the zipped file because the map is 11x17
 
Korea: Race to Pusan is an introductory level wargame covering the first weeks of the 1950 invasion of South Korea by the communist North Korea. The successful resistance by the South Koreans with whatever help the USA could rush to the warzone bought enough time for the USA to counterattack by landing at Inchon.

If the Communists had won the race to Pusan, the only major port in the far south, the United Nations would have been faced with accepting their aggression or mounting an amphibious invasion from bases in Japan.
