Major General Carlos Brewer (5 December 1890 – 29 September 1976) was a United States Army officer who commanded the 12th Armored Division during World War II.

[3] Many of the graduates of the West Point Class of 1913 later became general officers, including Alexander Patch, Douglass T. Greene, Geoffrey Keyes, Willis D. Crittenberger, Charles H. Corlett, Paul Newgarden, William R. Schmidt, Robert L. Spragins, Louis A. Craig, Selby H. Frank, Henry B. Lewis, Henry B. Cheadle, John E. McMahon, Jr., Richard U. Nicholas, Robert H. Van Volkenburgh, Robert M. Perkins, William A. McCulloch, Francis K. Newcomer, Lunsford E. Oliver and Henry B. Cheadle.

[4] Upon graduation from West Point in 1913, Brewer was commissioned as a second lieutenant and was assigned to the 3rd Field Artillery at Fort Sam Houston, serving along the Texas border until 1916 during the Mexican Revolution.

[3][4] His immediate predecessor as head of the Department of Gunnery, who was also an instructor when Brewer took advanced coursework there, was Jacob L. Devers, who would remain a lifelong friend and later prove providential in the course of his career.

While his wife was convalescing due to tuberculosis, he became head of the Military Science Department of the ROTC Program at Purdue University, the largest field artillery unit in the Army at the time.

In 1941, he was then transferred to Fort Benning, GA to command the 7th Field Artillery Regiment, where he developed the triangular division organization that was adopted during World War II.

After 2 months of courses at the Naval War College, he served as Assistant, then Chief of Staff (G-3) for the newly activated 9th Infantry Division, now commanded by his mentor, Major General Jacob L. Devers, at Fort Bragg, NC from August 1940 to February 1942.

[1] Despite the 12th Armored Division receiving excellent ratings in its final evaluation of readiness for combat service, Brewer was relieved of command and assigned to training replacement troops at Camp Wheeler, Georgia.

[8] Brewer had missed combat duty during World War I because he had been on the faculty teaching at West Point and was not enamored with having a non-combat command again.

Devers was by now in command of the newly formed Sixth United States Army Group leading the Allied invasion in the south of France, which consisted of the U.S.

Brewer began its combat operations in January 1945 in the Vosges Mountains, providing heavy artillery support for the VI Corps, commanded by Major General Edward H. Brooks.
