INFANTRY DIVISIONS

Various elements of the 4th through 9th Divisions remained on active duty until those divisions’ full activation prior to World War II.

The 76th through 91st and 94th through 104th Divisions existed primarily as officer billets with enlisted cadre; they were not completely reactivated until America’s entry into World War II.

The infantry brigades, field artillery brigades, and several other of the subordinate units of the Panama Canal, Hawaiian, and Philippine Divisions were numbered accordingly with what should have been the 10th, 11th, and 12th Divisions.
