Moreso for the North Koreans than the Chinese. The North Koreans were almost entirely outfitted with Soviet manufacture war materiel and equipment, but the Red Chinese had very little standardization even among frontline units, with a very heterogeneous mixture of American Lend-Lease, Soviet surplus, interwar European imports, and domestically produced unlicensed clones of all the above.I wish there were more miniatures and army men for the Korean War era.
Yeah, the American G.I.'s and British troops can easily be represented using World War II figures but the same cannot be said of the North Koreans or Red Chinese.
Although, I suppose you could use WWII Soviet troops as an impromptu stand-in for the North Koreans and Chinese in a Korean War scenario.
