Which operation involved Afghanistan with train, advise, and assist missions?

• A. Operation Highroad.
• B. Korea Peninsula Operation.
• C. Operation Gateway.
• D. Exercise Cope North.

Answer: (A)

Training, advising, and assisting partners means you help build the other nation's security forces from the inside—mentoring their troops, training officers, and enabling their institutions so they can lead and sustain security operations themselves, rather than conducting combat operations yourself. In Afghanistan, the operation that embodied this approach focused on developing Afghan capabilities through hands-on mentorship and support, rather than direct combat leadership. The other options do not fit Afghanistan’s capacity-building focus: one is tied to Korea, another to a Pacific air exercise, and the last to a different, unrelated mission.
