I want to know the answer to the following question:
What was the arm that was the Air Defence of the Ground Forces?
All the background I'm provided with is that "This was divided into two arms, PVO Strany, the Strategic Air defence Service responsible for Air Defence of the Homeland, created in 1941 and becoming an independent service in 1954, and PVO SV, Air Defence of the Ground Forces.". Is that enough to answer the question?
Answer: yes
