Final answer:
During the Vietnam War, there were three categories for NCOES deferment: draft deferments for college, exemptions for skilled workers in the military industrial complex, and officer training programs. These deferments allowed some individuals to avoid the draft or volunteer for a specific military branch.
Step-by-step explanation:
The three categories for NCOES deferment during the Vietnam War were:
- Draft deferments for college: College students were allowed to postpone their military service until they completed their education.
- Exemptions for skilled workers in the military industrial complex: Skilled workers who were deemed crucial to the war effort were exempted from the draft.
- Officer training programs: White middle-class youth were given the option to volunteer for officer training programs, which would allow them to choose the military branch they served in.
These deferments and exemptions resulted in less than one-third of White men being drafted during the war.
