Glossary of British Empire Military Abbreviations
There is no single source - no one book, web site or paper - that lists all of the thousands of military abbreviations and acronyms in use during the time that the Lee-Enfield rifle was in active production, 1888 - 1976.  Regiments contracted and expanded, countries were born, changed names, came and went.  Our focus is on regiments and unit organization, not chain-of-command.  As we encounter the acronymns or other useful terms in our research we will post them as time allows. Whenever practical the far right column will include the source information.
