WW2 Abbreviations and Acronyms

When you research a soldier who served in either the British or Indian Army during the Second World War you’ll be confronted by a wide range of military jargon.┬áThis jargon is often in the form of abbreviations and acronyms and can make reading military documents very difficult. To further complicate matters, you will often find multiple abbreviations and acronyms together.

Below is a list of abbreviations and acronyms which you may come across while researching a soldier who served in the Second World War. This list is by no means complete and also includes abbreviations and acronyms found both prior and post-war. Many soldiers who served in the Second World War also saw service in the First World War. The two links below will take you to pages containing abbreviations and acronyms on my website Researching WW1:
