I want to know the answer to the following question:
How many brigades did the Secretary of Defense increase the number to?
All the background I'm provided with is that "During the 1960s the Department of Defense continued to scrutinize the reserve forces and to question the number of divisions and brigades as well as the redundancy of maintaining two reserve components, the Army National Guard and the Army Reserve.". Is that enough to answer the question?
Answer: no
