Editing V Corps (United States) (section)

===Interwar period===

The V Corps was constituted in the [[United States Army Reserve|Organized Reserve]] on 29 July 1921, allotted to the Fifth [[Corps Area]], and assigned to the [[Second United States Army|Second Army]]. The corps headquarters was activated on 17 February 1922 at [[Fort Thomas, Kentucky]], with Regular Army and Organized Reserve personnel. The Headquarters Company was allotted to the [[Ohio National Guard]], but was placed on the "Deferred National Guard" list on 2 July 1923 and allotted to the Organized Reserve.

The Headquarters Company was initiated late 1924 with Reserve personnel at [[Columbus, Ohio]]. The corps headquarters was responsible for providing and planning administration, organization, supply, and training for army, corps, and other non-divisional Reserve units, less field and coast artillery, in the [[Fifth Corps Area]]. The headquarters was relieved from active duty on 15 November 1924, and all Regular Army personnel were reassigned to the Headquarters, Non-Divisional Group, Fifth Corps Area, which assumed the responsibilities previously held by the V Corps. Both the Headquarters and Headquarters Company remained active in the Organized Reserve. The corps headquarters was relocated in late 1924 to [[Indianapolis, Indiana]], where most of the Reserve personnel assigned to the unit were located. Headquarters, V Corps was withdrawn from the Organized Reserve on 15 August 1927 and allotted to the Regular Army; Headquarters Company, V Corps was withdrawn from the Deferred National Guard list on 15 September 1927 and permanently allotted to the Organized Reserve.

The headquarters company was further withdrawn from the Organized Reserve on 1 October 1933 and allotted to the Regular Army. At the same time, the corps headquarters was partially activated at [[Fort Hayes]], [[Ohio]], with Regular Army personnel from the headquarters, Fifth Corps Area, and Organized Reserve personnel from the corps area at large. Though a "Regular Army Inactive" unit from 1927 to 1940, the corps headquarters was organized provisionally for short periods using its assigned Reserve officers and staff officers from Headquarters, Fifth Corps Area. These periods of provisional active duty were generally for command post exercises and major maneuvers. Headquarters, V Corps was fully activated on 20 October 1940, less Reserve personnel, at [[Camp Beauregard]], LA.{{sfn|Clay|2010a|p=154}}
