Brigadier General Sereno Elmer Brett (October 31, 1891 – September 9, 1952) was a decorated United States Army officer who fought in both World War I and World War II and played a key, if little recognized, role in the development of armored warfare.

Early life and military career

Brett was born on October 31, 1891 in Portland, Oregon as a son of James Brett, and Clara Marie de Lille Harvey. Brett enrolled at Oregon State University and earned his Bachelor of Science at the Agricultural faculty in 1916. After his graduation, Brett entered the United States Army and, after attending a training course for officers, he was commissioned as a second lieutenant into the Infantry Branch of the Oregon National Guard, on November 28, 1916.

He first saw active service with the 3rd Infantry Regiment (The Old Guard) during the Pancho Villa Expedition. During World War I, Brett was ordered to join the American Expeditionary Force (AEF), under the command of General John Pershing, on the Western Front in Belgium and France, to serve with the Tank Corps. He was promoted to the rank of captain on July 25, 1917.

Commanding the 326th Tank Battalion, Brett, now a major, led the first major American tank attack of World War I at the Battle of Saint-Mihiel in September 1918 and, following Colonel George Patton's wounding, took command of the 1st Tank Brigade in his absence. Brett received the Distinguished Service Cross for his role in the battle. The Great War came to an end soon after, on November 11, 1918. In addition to the DSC, his other decorations from the war were: two Silver Stars, three Purple Hearts, French Croix de guerre 1914–1918 with palm and Officer of the Legion of Honour.
