Military Manuals

Created 25 September 2023

This is a semi-comprehensive attempt to try and gather as much military manuals as possible into one easy to locate location.

Due to me being in the USA; along with the US Government's view of US Government Publications being copyright free, most of the manuals here will be US in scope; as the British Government's Crown Copyright lasts for 50 years after date of publication, meaning that the latest UK manuals we can get (in 2023) will be from 1973 or earlier.

Background to US Army Military Manuals
(Written by Military/Info Publishing)

Early Military Manuals

Until the 1890’s there were no army manuals in the current sense. Military manuals before the 1890’s were foreign imports or privately published manuals and textbooks, without any numbering. For all practical purposes they were simply books, with an author and title.

From the late 1880 until the end of First World War military manuals were either War Department Documents or Ordnance Department Documents. Both types of documents were numbered consecutively (1,2, 3, etc.) as they appeared with no variations concerning subject matter. But there was often a branch numbering system superimposed on the manual. For example War Department Document No.541 could also be Signal Manual No.3.

War Department Documents were approximately similar to modern Field Manuals with an occasional one concerned with a technical subject like signal communications and were usually hard covered books. Ordnance Department Documents were similar to modern Technical Manuals and could be either hard cover or paper backed.

After the First World War

Manuals began to be issued in loose leaf form designed to be placed in binders, numbering prefects including TR (Training Regulations), TM (Training Manuals), and TC (Training Circulars), with TR’s being the most common type. There Prefixes were followed by a two to four digit number then a dash followed by a two to three digit number. Like “TR 50-70 or TR 425-30”. The first set of numbers noted the subject while the second set noted the number of the book under the subject. The subject number system was fairly complex. Unfortunately too complex for the length of this essay.

The Technical subjects of the earlier Ordnance Documents were incorporated into the Training regulation system.

The Late 1930’s

The Training Regulations were merged into a series of branch Field Manuals, like Basic Field Manual, Cavalry Field Manual, etc. The Field Manuals of this period did not have a number system like current manuals. Instead FM 21-75 they are titled by subject like “Basic Field Manual, Volume I, Chapter 3”.

World War Two and After

The current U.S.Army manual number system was started at the beginning of the Second World War. The primarily types of manuals became either FM’s (Field Manuals), or TM’s (Technical Manuals), later followed by a bewildering arrangement of lesser Prefixes like TC (Training Circulars). ST (Special Texts), FC (Field Circulars), just to name a few.

Field Manuals were usually numbered by a one to two digit number followed by a dash followed by a one to two digit number, like “FM 21-75”, with the first series on numbers being the subject classification of the manual and the second series being the particular manual.

Technical Manuals were numbered at first like FM’s, but because they were vastly more of them by the early 1960’s, they began to be changed to a more complex system.

Early TM’s have numbers like “TM 9-2300”. The first number being the subject or branch of the Army. Number “9” means that it is an Ordnance Branch manual. The second series of numbers referring to the particular manual.

The many later TM’s, concerned with single pieces of equipment, especially Ordnance equipment, were numbered like “TM 9-1005-223-12”. The first number refers to the branch. The number “9” means that it is an Ordnance branch document. The second series of numbers refer to the subject type. The third series refers to the particular piece of equipment or subject. The four series on numbers refer to the level of maintenance which the manual is concerned with. With “10-12” being operator and organizational maintenance level, and with higher numbers concerned with a higher level, 20’s being direct support, 30’s being general support.

While this essay can only give the reader a brief snapshot of the coding system, I hope that it will clear up some confusion.

US Army FM/TM Numbering Explained

It used to be under the 1940s system that a FM/TM would have a two sequence designation:

Basic Number
and
Subnumber

Where subnumbers 0 to 199 were assigned to field manuals and 200 and up were given to Technical Manuals.

For nearly sixty years, US Army FMs conformed to the basic categories set down in the 1940s for Basic Number Series, but from the 2000s onwards, they started to renumber the manuals to be “Joint”.

FM 3-5 Tactics and Technique (1 August 1938)
FM 3-5 Tactics of Chemical Warfare (20 July 1942) – 11.49 MB PDF (would get C1, 2 later)

NOTE: FM 3-5 and 3-6 (1946) were post-war “cleanups” of work that was already well underway when the Japanese surrendered in August 1945. You can figure this out by the number of references to specific wartime situations that crept into these manuals. Because of their extreme importance in representing “field tables” for the use of Chemical Weapons circa Summer 1945, I have taken the rare step of OCRing both manuals completely; hence the hyperlinks below, in addition to the PDF document links.

FM 3-5 Characteristics and Employment of Ground Chemical Munitions (1 May 1946) (409 MB PDF) (30.2 MB Shrunk PDF)
(Copy from University of Virginia, Charlottesville, VA)

FM 3-6 Employment and Characteristics of Air Chemical Munitions (1 October 1946) (367 MB PDF) (25.2 MB Shrunk PDF)
(Copy from University of Maryland, College Park, MD)

The reason for the massive file sizes is that I had to use the document scanner at University of Maryland's McKeldin Library to scan both Field Manuals; and even that high end scanner doesn't have the 'voodoo' that Google Books' project does. So there's a lot of blurry and out of focus pages; and I don't want to take the chance of losing information totally by reducing their file size down to 2-bit binary.

I have included a “shrunk” version for each of them, using Adobe Acrobat's “Reduce File Sizes” option, for those of you on limited bandwidth connections.
