Brief Border Wars 2 is the second release in Brian Train’s series of easy-to-learn small operational-level games on short border conflicts. The card-driven system models the chaotic, stop-and-start nature of these impromptu wars. Four sets of exclusive rules reflect the peculiar nature of each conflict covered. The players’ sense of improvisation will be challenged as they explore four of the more interesting small wars fought in the early 20th century. This quad-game includes 1913: Second Balkan War (also known as “The Interallied War”), 1919: The Seven-Day War (also known as "Teschen"), 1939: The Nomonhan Incident (also known as "The Battle of Khalkin Gol"), and 1940: The Italo-Greek War (also known as "The Balkan Defiance").
