Yeoman (YN) A-School Test 2 Practice

The senior enlisted adviser to the commanding officer on a Navy vessel or unit is the Command Master Chief (CMC) or an equivalent senior enlisted leader. This person acts as the primary liaison between the commanding officer and the enlisted crew, advising on matters that affect enlisted personnel—morale, welfare, discipline, training, and overall readiness. They ensure Navy policies and standards are understood and implemented at the enlisted level and mentor the chiefs and petty officers who lead the crew day to day. The executive officer is a commissioned officer serving as the CO’s deputy, the Master Chief Petty Officer of the Navy is the Navy-wide senior enlisted leader, and the Supply Officer handles logistics—not the relationship between the CO and the enlisted force on that ship or unit.
