the mid-1920s, most of the divisions' inactive units were staffed with Organized Reserve officers as Regular Army Inactive units. The Hawaiian Division, "which was the closest thing to a full-strength division in the interwar American Army." was split on 1 October 1941 to create the 24th and 25th Infantry Divisions. The 24th Infantry Division headquarters inherited the lineage of the Hawaiian Division's headquarters, while the 25th Infantry Division was raised in the Army of the United States. The 10th Mountain Division was raised in the Army of the United States in 1943. 26th to 45th The 26th through 45th Divisions, with the exception of the 39th and 42nd Divisions, were raised in the National Guard during and after World War I. In postwar mobilization plans, the 26th through 45th Divisions, less two, were allotted to the National Guard. The 30th, 31st, and 39th Divisions had been organized in what would become the states of the Fourth Corps Area; the designations of the 30th and 39th Divisions were originally selected, with the 31st Division being deleted. In 1923, the adjutants general of the states concerned successfully requested that the War Department change the designation of the 39th Division to the 31st Division and adjust allotments of units accordingly. The 42nd Division was the second division deleted from the mobilization program as it had contained units from twenty-six states and the District of Columbia, although it would be reconstituted during the war as a division in the Army of the United States. 63rd to 89th After World War I, 33 infantry divisions (the 76th through 104th) were organized as part of the Organized Reserve. They were nominally regional organizations, drawing their officer cadre and a small, nearly insignificant, number of enlisted men from an allotted portion of a state, entire state, or multiple states, similar to National Guard units. Prior to American involvement in World War II, Organized Reserve officers were called to active duty individually and assigned to existing Regular Army and National Guard units. When the Organized Reserve units themselves were called to active duty beginning in 1942, "few of the Reserve officers originally assigned to...units were available for duty with them. Consequently, the units as activated bore small resemblance to those of peacetime." The 61st, 62nd, 67th, 68th, and 72nd-74th Infantry Divisions were constituted, but never activated. They were dropped from the mobilization program in 1943. 90th to 106th
