I've re-uploaded some U.S. Army & Marine Corps Reference Data publications from places like the U.S. Army Heritage and Education Center. I've optimized the PDFs (the originals were 100-300MB+) and labelled them a little better so hopefully they're more searchable than on the USAHEC site. These are primary source documents.


These visualize Tables of Organization and Equipment in a very detailed way, and sometimes include other things like logistical data, missions, capabilities and other info. They often include every subunit in a division down to the personnel level.


U.S. Army

  • "Infantry Reference Data" (March 1961) D-series reference data covering the final Pentomic organization of Infantry Divisions, and to a lesser extent Airborne and Armored Divisions.

  • "Infantry Reference Data, ROAD" Part 1 and Part 2 (September 1962) E-series ROAD reference data, the organization that replaced Pentomic. Part 1 covers Armored, Infantry and Mechanized Divisions, and the Airborne Division base (less its logistical Support Command and maneuver battalions). Part 2 covers the Airborne Division Support Command and the maneuver units attached to the division base, as well as Separate Brigades and communications and logistical reference data.

  • "Infantry Reference Data" Part 1 and Part 2 (June 1967) G-series ROAD reference data. Part 1 includes Infantry, Mechanized Infantry, and Armored Divisions, Separate Infantry/Armored Brigades, the Airborne Division and Airborne Division Brigade HHCs, Airborne Division Military Police Company, and part of the Airborne Division Aviation Brigade. Part 2 includes the remainder of the Airborne Division, Separate Airborne Brigade (Brigade Base units are F-series), and Airmobile Division (Tentative).


U.S. Marine Corps

  • MCS 3-55 "Organization and Employment of Marine Corps Field Artillery Units" (2 July 1962) M-series reference data for field artillery organizations within the Marine Division and the Force Troops (FMF). It covers divisional Artillery Regiment (with HQ Battery, General Support Battalion, and 3 Direct Support Battalions), Force Artillery HQ Batteries, Field Artillery Groups, 155mm SP batteries, 8" SP batteries, and Honest John batteries. Half the document is organizational (although not TO&E-level detailed), and the other half is on tactical employment, planning for amphibious operations, fire planning, etc.
