Ho Chi Minh trail
Soviet troops, notably Georgy Zhukov, used the concept during the Khalkhin Gol campaign (1939) and in World War II (1941-1945). North Korean troops also used such structures during the Korean War (1950-1953), particularly to cross the Naktong River during the Battle of Pusan Perimeter of August-September 1950. In the Vietnam War the Ho Chi Minh trail used such bridges.
