U.S. Army & U.S. Marine TO&Es (WWII)

Archive > World War II > WWII U.S. Sources

This is the collection of U.S. Army and U.S. Marine TO&Es of World War II that I have come across online. It will also have TO&E adjacent sources, like reference data books, and letter, memos, or other documents that provide context to unit organization.

I am choosing to upload only original TO&Es, not manual copies, to prevent the transcription errors that have showed up in my past articles. Plus the secondary online sources that I list under "TO&E Re-copies & Other Sources" provide as much TO&E information as most people would ever want.

TO&E Re-copies & Other Sources

• MilitaryResearch.org (Archived) - TOE Format Tables. Includes both Technician Ratings for specific roles and SSNs (MOS). Has a significant amount of U.S. Army TO&Es from the 1943-1944 period available, as well as a smaller number of miscellaneous U.S. Marine, U.S. Navy and U.S. Army Air Forces TO&Es.

• WarEstablishments.net (Defunct as of Jan 2026) - TOE Format Tables. Does include Technician Ratings for specific roles but not SSNs. This is a Wayback Machine link for a defunct website that has a lot of TO&E and War Establishment digitizations. While the site as a whole is focused on Commonwealth forces, there are a lot of U.S. TO&Es as well.

• BayonetStrength (Archived) - Simplified TOE Format Tables and lists. Does include Technician Ratings for specific roles but not SSNs. Gary Kennedy's site focuses mostly on Infantry Battalions during World War II and also has companion pdfs that talk about the changes in context.

• Igor Chub (Archived) - Graphic Interpretation. Does include a recapitulation of number of Technicians (1942 and onwards), Privates First Class, and Privates in a company. Does not include Specialist Ratings (pre-1942) at all, which roles had Technician Ratings (1942 and onwards), or SSNs. A gold mine of information on the early 1940-1941 U.S. Army that is often missed, as well as some more niche stuff like US Harbor Defense, US Army Air Force, US Marine (including aviation squadrons), and US Navy Cruiser (CL-6/CA-31) TO&Es. It's done in the more graphical style of Christoph Widmann-Awender's equivalent site on German WWII KStNs, so it's easier to read but isn't a one-for-one copy of the TO&Es and loses some of the detail.

• The Nafziger Collection (Archive) - Lists. Sometimes includes recapitulations of the Technicians or Specialists, Privates First Class and Privates in a company, but does not generally list what roles specifically had Technician ratings (they're all listed as Privates). Also does not include SSNs. Arguably the most famous collection of TO&E-derived information, and possibly one of the most expansive at over 10,000 files. It's actually much more than just TO&Es, with a lot of orders of battle as well going back to the 1600s. With WWII U.S. TO&Es though it misses out on a lot of detail. They're recounted exclusively in list form, so are easier to read than a TO&E, but doesn't recount Specialist/Technician ratings and is sometimes inconsistent with the information when you jump between company TO&Es and their higher units.

• John Sayen's "Battalion: An Organizational Study of the United States Infantry" (Document and Appendix with TO&Es) - Document is a Narrative and Appendix is Chart-Type Interpretations. Mislabels Specialist Ratings pre-1942 as Technicians but makes a good effort at describing which roles held which Specialist/Technician Ratings. Does not include SSNs, though. Probably the holy grail of secondary sources on the evolution of U.S. Army and Marine Infantry Battalion and Regiment (but not post-Interwar Brigade) organization from the 19th century to about 2001. The appendix is a great quick reference, although because of how it is formatted it's hard to tell if somethings are actually how they were written in the original TO&Es or author interpretations for brevity's or consistency's sake.

• HyperWar - A great site in general but has some useful recapitulation tables of U.S. Marine Divisions in particular:

  • D-100 (1 Jul 1942)

  • E-100 (15 April 1943)

  • F-100 (5 May 1944)

    • F-series Infantry Regiment and subunits in detail

  • Recapitulation tables of D-, E-, F- and G-series Marine Infantry Regiments

  • Staff Officer's Field Manual for Amphibious Operations-Organization, Technical, and Logistical Data (10 September 1944)

• Yves J. Bellanger's Books - Not free, but some of the best if you want to get a detailed picture of the TO&E of every subunit in a division type. TO&E information is provided both in list and graphical formats, and there are also excerpts from doctrinal publications. Here are affiliate links to the books out as of January 2026:

  • U.S. Army Infantry Divisions 1943-1945

  • U.S. Army Armored Division 1943-1945

  • U.S. Army Heavy Armored Division, Volume 1, 1942-1943

• Leo Niehorster's Website - Chart Type Interpretations. Information is kind of general at the lowest levels. Personnel are usually listed as Officer, NCO, or Enlisted and only key weapons and vehicles are listed. Very detailed if you are mainly focused on the division and regiment-levels though. Has a lot of complete information for all types of units spanning the whole war, including both divisions and non-divisional units.

• Shelby Stanton's "Order of Battle, U.S. Army, World War II" (1984) which you can borrow for free with an account on Internet Archive. Not a TO&E source per se, but a very extensive look at the order of battle of the U.S. Army during the war, with information on units from all arms from separate battalion to division. This includes campaign credit, ship out dates, information on reflagging or unit conversions, and in some cases the date the unit adopted a certain TO&E (this is the case for Tank Battalions). For divisions their typical organization is also listed.

 Reference Data books

Army manuals that summarize TO&E information (among other things) for training purposes. The information is generally quite expansive, but not the most detailed and has a data cutoff date well before the publication.
