I want to know the answer to the following question:
What is the Russian term for air defence?
All the background I'm provided with is that "English terms for air defence include the German Flak (Fliegerabwehrkanone, "aircraft defence cannon", also cited as Flugabwehrkanone), whence English flak, and the Russian term Protivovozdushnaya oborona (Cyrillic: Противовозду́шная оборо́на), a literal translation of "anti-air defence", abbreviated as PVO.". Is that enough to answer the question?
Answer: yes
