Chosin: X Corps Escapes the Trap, is a two-player, intermediate-complexity simulation of the fighting in eastern North Korea in late 1950 in which the Chinese attacked the United Nations X Corps as it approached the Yalu River. One of the more famous incidents of the campaign was the US Marine Corps 1st Division fighting its way out of an envelopment at the Chosin Reservoir. Chosin, designed by Joseph Miranda, covers the entire campaign using the same game system as Gauntlet, which appeared in Strategy & Tactics 190. The two games are compatible, and the Strategic Scenario included in this issue provides instructions, as well as extra units, to create a combined Chosin/Gauntlet game of the entire Chinese offensive of 1950. Players can also use the Chosin rules and charts to update Gauntlet.
