The Big 3

Who is the Big 3?

The 'Big 3' consists of the Commanding Officer (CO), Executive Officer (XO), and Senior Enlisted Leader (SEL). As the two highest ranking cadets, the CO and XO serve as a bridge between the Naval Science Instructors and the cadets. The SEL serves as a bridge between the enlisted cadets and the cadet officers.

Each has their own set of responsibilities which they carry out to keep the Unit in top performance, boost cadet morale, and represent Great Mills High School.
