Heinz Guderian vs Henry Hap Arnold

Guderian commanded the XIX Army Corps during the invasion of Poland, leading armored and motorized units in a rapid advance. His tactics demonstrated the effectiveness of blitzkrieg, resulting in the swift defeat of Polish forces.

Guderian led the XIX Panzer Corps through the Ardennes Forest, crossing the Meuse River at Sedan. His rapid advance cut off Allied forces in Belgium, leading to the Dunkirk evacuation and the fall of France.

Guderian commanded Panzer Group 2 in the invasion of the Soviet Union. His forces captured Smolensk and advanced to within 200 miles of Moscow, but were halted by Soviet resistance and the onset of winter, failing to take the capital.

Guderian was dismissed from command after withdrawing his forces without Hitler's permission during the Battle of Moscow. He was recalled in 1943 as Inspector General of Armored Troops, tasked with rebuilding Germany's panzer forces.

Arnold was appointed Commanding General of the US Army Air Forces, overseeing the expansion of the air force from 20,000 to 2.5 million personnel. He directed the strategic bombing campaigns in Europe and the Pacific.

Arnold was promoted to five-star rank as General of the Army, and later became the only officer to hold five-star rank in two US services when he was also made General of the Air Force. This recognized his role in creating an independent air force.

Arnold championed the development and production of the B-29 Superfortress, the most advanced bomber of World War II. The B-29 was used for strategic bombing of Japan and ultimately dropped the atomic bombs.

Arnold was a key advocate for the creation of an independent US Air Force, separate from the Army. The National Security Act of 1947 established the Air Force as a separate service, fulfilling Arnold's long-term goal.
