English is the language most frequently used in international military and peacekeeping operations. This dictionary aims to provide a basic vocabulary of British and American terms relating to the three services, and covers subjects such as rank, organization, training, operations in the field, logistics, radio communications, and some of the more common weapons and equipment currently in use. In addition, there are selected items of general vocabulary relating to geography, terrain, weather, medical treatment and other relevant matters. New terms used by the media in reporting on recent conflicts are also included, making this an ideal reference source for anyone involved in teaching English to the military or armed police forces.
