Military & Armed Forces

Squaddie slang, wartime expressions, and forces culture

Introduction

The British military has contributed enormously to everyday English, often in ways speakers don't recognise. Expressions from two world wars, colonial service, and generations of squaddies have enriched the language with vivid, often darkly humorous vocabulary.

Military slang serves practical purposes—efficiency, camaraderie, and the gallows humour needed to cope with danger. Terms like "civvy street," "AWOL," and "going commando" have crossed into civilian use, carrying echoes of their military origins.

This chapter explores the vocabulary of British military life—from ranks and equipment to the banter between regiments. Many of these terms come from conflicts that shaped modern Britain, making this vocabulary a window into national history.
