Notes
The interwar US Army's basic tactical formation was the infantry division. Organizationally, the division had changed little since World War I: It was still a "square" division with two infantry brigades controlling two infantry regiments each and an artillery brigade controlling three field artillery regiments. With a total of twelve infantry battalions and six field artillery battalions, the square division was a powerful but somewhat unwieldy unit.
Infantry regiments consisted of a regimental headquarters company, three infantry battalions, a regimental cannon company, a regimental machinegun company and a regimental service company. Field artillery regiments consisted of a regimental headquarters company, two field artillery battalions, an observation battery and a regimental service battery.
The division train was responsible for supply and transportation, and the field artillery brigade had its own ammunition train.

BRIGADE Right:
52nd INFANTRY BRIGADE

51st FIELD ARTILLERY BRIGADE
Infantry divisions were authorized distinguishing flags with two equal horizontal stripes, scarlet over national flag blue, and the divisional shoulder sleeve insignia in proper colors centered. For brigades, the flags were national flag blue for infantry and scarlet for field artillery, with the numerical designation of the brigade centered in white and yellow respectively. The flags were made of wool bunting, 3 feet at the hoist by 4 feet on the fly.

Headquarters companies and batteries of divisions and brigades had guidons similar to the brigade flags, but with the designation HQ added. These and all other guidons were made of wool bunting, 1 foot 8 inches at the hoist by 2 feet 4 inches on the fly, with a 10-inch fork.

Regimental Headquarters
Company, 101st Engineers

Left: Company C, 26th Infantry Division Train
Right: Company B, 51st Field Artillery Brigade Ammunition Train
Guidons for infantry, field artillery and engineer regiments were similar to those used today, but since line companies and batteries were lettered in sequence regardless of battalion assignment, no battalion numeral appeared on their guidons. The guidon of the regimental headquarters company had the designation HQ below the branch insignia and battalion headquarters companies had the battalion number below the insignia. The companies of the division's supply and ammunitions trains also had branch oriented guidons. In the case of the latter, the badge was a combination of the Field Artillery (crossed cannons) and Ordnance Corps (flaming bomb) branch insignias.
