Adna Romanza Chaffee Jr. (September 23, 1884 – August 22, 1941) was a major general in the United States Army, called the "Father of the Armored Force" for his role in developing the U.S. Army's tank forces.
Chaffee was the son of Lieutenant General Adna R. Chaffee. Born in Junction City, Kansas, on September 23, 1884, he was commissioned a Lieutenant of Cavalry in 1906 after graduating from the United States Military Academy, and won recognition as the "Army's finest horseman."
Upon his father's death in 1914, he became an Hereditary First Class Companion of the Military Order of the Loyal Legion of the United States.
In World War I, he was an Infantry Major with the IV Corps during the Battle of Saint-Mihiel. As a Colonel, he later served with the III Corps throughout the Meuse-Argonne Offensive.
Following the war, he returned to his Regular Army rank of Captain of Cavalry and became an instructor at the General Staff School and the Army School of the Line at Fort Leavenworth. During the 1920s, he helped develop the armor concepts and doctrine of the future. He predicted in 1927 that mechanized armies would dominate the next war and assisted in the first program for the development of a U.S. Army armored force. Assigned to the 1st Cavalry Division in 1931, he continued to develop and experiment with armored forces, thus becoming the leading American advocate of mechanized warfare.
