The MOS changed from 71B to 71M in August 1965 due to changes to which Army Regulation?

• A. January 1963 as a result of AR 611-201
• B. August 1965 when AR 611-201 caused the MOS to change from 71 B to 71M
• C. October 1972 as part of an Army-wide MOS realignment
• D. June 1958 during the Korean War era

Answer: (B)

MOS designations are set and updated by Army Regulations. In August 1965, an amendment to AR 611-201 reorganized the 71-series occupations, changing the designation from 71B to 71M. The change reflects a regulatory realignment of job codes, not a new job addition or a date-specific milestone outside the AR 611-201 update. That August 1965 revision is what caused the MOS to switch from 71B to 71M. The other dates are not the regulation-driven reason for this specific change.
