model. Goose stepping continued to gain ground even after Germany's defeat in World War I, as many nations still looked to the German model for military organization and training. The Chilean Army was the first non-European country to adopt the goose step, importing many Prussian military traditions after the War of the Pacific. The practice of goose stepping then spread widely throughout Latin America from Chilean influence. Meanwhile in Asia, the Beiyang New Army of Imperial China also adopted goose stepping together with Prussian military model. After its dissolution, the National Revolutionary Army of the successive Republic of China continued the practice, also because that they were being trained by German advisers in the 1920s; after the Communists won the Chinese Civil War, the People's Liberation Army of People's Republic of China would follow suit and bring the practice into present day, owing to both tradition and its own Soviet influence. They account for the largest single goose-stepping military today. Cold War During the Cold War, the Soviet Union trained the military forces of many of its client states with Soviet military drill and ceremonial practices. This led to the second great wave of goose step adoption, as it was introduced into many Third World countries in Asia and Africa. Meanwhile, the United States, United Kingdom, and France were, through efforts in their client republics and allies, preventing the use of the goose step in their armed services. A divided Germany was also divided in their armies' foot drill; the East German Nationale Volksarmee kept the goose step, while the West German Bundeswehr only kept the Gleichschritt (quick march). The centuries-long German practice of goose-stepping finally ended in 1990, when the former was absorbed into the latter due to German Reunification. Usage Ceremonial usage The goose step is a difficult marching style that takes much practice and choreography in order to coordinate the timing of each person's step with one-another. It is therefore reserved for ceremonial occasions such as military parades. Because it is difficult to maintain for long periods of time, troops typically only begin to goose-step when they approach the reviewing stand and return to a normal march step once they have marched past. Large military parades require several days of practice to ensure that troops can perform the goose step without injuring themselves. Preparatory training includes having soldiers march in small groups, with arms linked to maintain
