Upon returning to the United States, the division was stationed at Fort Sam Houston, at San Antonio, Texas as one of three divisions to remain intact and on active duty for the entire interwar period.
It remained there for the next 23 years, serving as an experimental unit, testing new concepts and innovations for the Army.
The 2nd Division stationed at Camp Bullis and Fort Sam Houston, Texas was the first command reorganized under the new triangular concept of organization theory of warfare, which provided for three separate regiments in each division.
Indianhead soldiers pioneered concepts of air mobility and anti-tank warfare, which served the army for the next two decades on battlefields in every corner of the globe.

The 2nd Division participated in maneuvers at Christine, Texas between 3 and 27 January 1940.
It then moved to Horton, Texas for maneuvers from 26 April to 28 May 1940, followed by maneuvers at Cravens, Louisiana from 16 to 23 August 1940.
It returned to Fort Sam Houston, where it continued training and refitting, until it moved to Brownwood, Texas for the VIII Corps maneuvers from 1 June through 14 June 1941 at Comanche, Texas.
The division was then sent to Mansfield, Louisiana from 11 August through 2 October 1941 for the August–September 1941 Louisiana Maneuvers.

The division was transferred to the VIII Corps Louisiana maneuver Area on 27 July 1941, being redesignated as the 2nd Infantry Division in August, and remained there until 22 September 1942, whereupon the formation returned to Fort Sam Houston.
They then moved to Camp McCoy at Sparta, Wisconsin on 27 November 1942.
Four months of intensive training for winter warfare followed.
In September 1943 the division received their staging orders, and moved to the Camp Shanks staging area at Orangeburg, New York on 3 October 1943, where they received Port Call orders.
On 8 October the division officially sailed from the New York Port of Embarkation, and started arriving in Belfast, Northern Ireland on 17 October.
They then moved over to England, where they trained and staged for forward movement to France.
