I want to know the answer to the following question:
What is the air defence of a certain area called?
All the background I'm provided with is that "Area air defence, the air defence of a specific area or location, (as opposed to point defence), have historically been operated by both armies (Anti-Aircraft Command in the British Army, for instance) and Air Forces (the United States Air Force's CIM-10 Bomarc).". Is that enough to answer the question?
Answer: yes
