From 1939 to 1941, Germany stunned the world with the introduction of Blitzkrieg, a new mode of war focused on massed armored spearheads and close air support. Rapid shock and encirclement by mechanised armies replaced the grinding attrition of World War I trench warfare. In this DLC, you command Wehrmacht forces during this period, starting with the 1939 invasion of Poland, through the daring airborne assault on Crete in May 1941.
