Page "Louisiana Maneuvers" Paragraph 8

The first U. S. Armored Division was tested in the maneuvers.

Built around a nucleus from Chaffee's 7th Mechanized Cavalry, the armored division tested the ability of a very large combined-arms mechanized unit to move long distances, maintain troops and vehicles in combat conditions, and affect the outcome of tactical and operational-level problems.

The armored division concept was considered sound and led to the formation of 16 U. S. Armored Divisions during World War II.
