How should cadets address non-commissioned officers?

Cadets should address non-commissioned officers by their rank and last name. This form of address reflects the respect and formality that is inherent in military traditions. Using a non-commissioned officer's rank recognizes their position and authority within the chain of command, which is essential for maintaining discipline and respect in a military setting.

Addressing them by rank and last name establishes clear lines of responsibility and hierarchy, which are crucial in training and operational environments. This practice not only fosters respect among cadets and their leaders but also reinforces the military's structure, where clarity in roles is vital for effective teamwork and performance.

The other options do not align with standard military customs; referring to non-commissioned officers by their first names, positions in the team, or job titles would fail to convey the necessary respect and acknowledgment of rank within the hierarchy.
