In the fall of 1923, the Cadet Corps, with a total of 2,091 cadets in twenty-three individual units, became divided between the Infantry Regiment and the Composite Regiment. The Composite Regiment included the Cavalry, Field Artillery, Air Service and Signal Corps units. The Air Corps Squadron (formerly Air Service Squadron) was phased out at the end of the 1927–28 school year. In the fall of 1928, with enrollment at 2,770 cadets, an Engineer Battalion was added, and the following year a third regiment was formed out of the expanded Field Artillery Battalion. A fourth battalion, the Coast Artillery, was added to the Composite Regiment in the fall of 1933.
