@OmSigDAVID,
Patton was a cavalryman, had been throughout his career. He was assigned to the cavalry upon his graduation from the United States Military Academy. He participated in the first modern pentathalon at the 1912 Olympics (two of the five events are shooting and equestrian). He studied with a master swordsman in Germany, and then
the master swordsman of the French army, and published his recommendations for a new cavalry saber in the
Cavalry Journal, and formally submitted his recommendations to the Ordnance office of the United States Army. He was the youngest man ever to be appointed the Sword Master of the United States Army, and he taught cavalry and saber tehcnique at the Mounted Service School at Fort Riley, Kansas. He participated in the 1916-17 expedition as a member of the 8th Cavalry, against Pancho Villa in Mexico. During that expedition, he conducted the first amored attack in American history with three armored cars. Arriving in France in 1917, Pershing asked to organize the first army light tank school. He learned to drive all the tanks available, visited Renault (who made the French tanks), drove the Renaults through the French trench system and made recommendations for the improvement of the vehicle. After the British armored attack at Cambrai, he went to study amored tactical doctrine with the British armored commander, J F C Fuller. In 1918, he was placed in command of the first provisional light tank brigade, which was later made one of the tank brigades of armored corps. He participated in two campaigns as an amored brigade commander before being sent to recuperate from wounds. After the war, he and Eisenhower developed at Fort Riley the amored doctrine which would be used in the U. S. Army in the Second World War. He made many innovations in armored vehicles and petioned Congress continuously (and usually unsuccessfully) for funds to expand and improve the armored corps.
If any officer in the United States Army was all cavalry and all armor, it was George S. Patton. He would have been wasted in MacArthur's campaigns.
