I want to know the answer to the following question:
Who was the Secretary of Defense in 1967?
All the background I'm provided with is that "In 1967 Secretary of Defense Robert McNamara decided that 15 combat divisions in the Army National Guard were unnecessary and cut the number to 8 divisions (1 mechanized infantry, 2 armored, and 5 infantry), but increased the number of brigades from 7 to 18 (1 airborne, 1 armored, 2 mechanized infantry, and 14 infantry).". Is that enough to answer the question?
Answer: yes
