Schwerpunkt, a German term meaning 'focal point' or 'main emphasis,' refers to the strategy used by the German military during World War II, particularly in the context of Blitzkrieg tactics. It involves concentrating forces and resources at a specific point to achieve a decisive breakthrough. This concept was central to Germany's rapid victories in the early years of the war, as it allowed for swift and overwhelming attacks against enemy positions, ultimately contributing to the swift fall of France.
