The 7th Cavalry Brigade was a brigade of the United States Army, active from 1932 to 1940. Colonel Daniel Van Voorhis took a cadre of 175 officers and enlisted men from Fort Eustis to Fort Knox in February 1932, and established a Provisional Armored Car Platoon. This was based on an earlier effort, but was predicated on a new Cavalry Regiment TO&E (Table of Organization and Equipment) which was published that year. Also published, but never implemented, was a cavalry division TO&E which reflected the then unnatural assimilation of machines into the Horse Cavalry. Van Voorhis's cadre and platoon became the kernel for the 7th Cavalry Brigade, which went active on 1 March 1932 at Fort Knox. At first, it was nothing more than a headquarters detachment and the Armored Car Platoon.
