The name cadet grey stems from its use in uniforms of the United States Army, in particular, cadets at the United States Military Academy at West Point, New York. Both armies in the American Civil War initially included uniforms in the color, including the 7th New York Militia, but it was primarily identified with those of the Confederate States of America. By 1863, all troops were asked to obey the Regulations for the Confederate States Army and have cadet grey uniforms. The lack of a formal uniform at the beginning of the war, with some Confederates wearing blue and some U.S.-allied state militias still wearing gray, caused significant confusion for both sides in the First Battle of Manassas. Cadet grey was previously chosen for the Army of the Republic of Texas in 1835 and 1840. Under the name "pike grey" (Hechtgrau) this color distinguished the jäger regiments of the Austrian (and subsequently Austro-Hungarian) armies from 1801 until 1915. In 1908 it was adopted as the universal color of the new field service uniform for the army as a whole. See also
