I want to know the answer to the following question:
What does CSA stand for?
All the background I'm provided with is that "The U.S. Army is headed by a civilian senior appointed civil servant, the Secretary of the Army (SECARMY), and by a chief military officer, the Chief of Staff of the Army (CSA) who is also a member of the Joint Chiefs of Staff.". Is that enough to answer the question?
Answer: yes
