Features of the translation of the slang of the British Air Force on the example of the military film “Battle of Britain”

World War II was the largest military conflict in the human history. This conflict affected both military relations between states and the development of the armed forces of many countries. The Air Force had the greatest development, including the RAF, which made Great Britain famous in the aftermath of the war by having a decisive influence on its outcome. The Air Force's missions included destroying enemy personnel and facilities, providing air cover for the Army and the Navy, as well as conducting air transfers and air reconnaissance. All of this has influenced the emergence of new slang terms in the language of the British military. In addition, in the twentieth century there was a rapid development of weapons and military equipment, which also influenced the military slang. Since the Second World War, a number of films have been made about the conflict. The authors of these films strive to show the life of soldiers during the war. That is why war films often use military slang, which makes them a great way to learn military slang terms. We consider the war film “Battle of Britain” (dir. By Guy Hamilton, 1969) for the presence of the military slang of the Royal Air Force and the translation of this film into Russian. In addition, we will make a thematic classification of slang and determine the ways of translating military slang into Russian. While training, military specialists, first of all, study the features of formal military discourse, which is why its informal part remains poorly understood. Therefore, upon completion of training, military interpreters often face problems in translating slang terms. Therefore, research in this area can help military specialists avoid mistakes during their professional activities.
