In 1938, Japanese forces attacked Chinese defenders over the Yangtze River at the Battle of Wuhan. Soon, the Japanese would later further improve its techniques upon seaborne assaults by the Second Sino-Japanese War. By World War II, marines such as the Special Naval Landing Force, used amphibious landings to attack and sweep across territories in South East Asia. Their technique of surprise landings in continuous success and the support from the Navy, inspired the British and American landings in World War II such as D-Day and the Pacific Campaign.
