Which duty falls under the Senior Medical Officer (SMO) on a navy ship?

The responsibility of ensuring crew health and wellness is a fundamental duty of the Senior Medical Officer (SMO) on a Navy ship. The SMO plays a critical role in overseeing the medical readiness of the crew, which includes providing medical care, health assessments, disease prevention, and health education. This position is essential for maintaining the overall well-being of sailors, especially in the unique living and working conditions on a ship.

By focusing on the health and wellness of the crew, the SMO can help prevent outbreaks of illness, manage medical emergencies, and promote a healthy environment, thus ensuring that all personnel are fit for duty and capable of performing their tasks effectively. This duty is aligned with the Navy's commitment to maintaining the safety and operational readiness of its personnel.

In contrast, the other options involve different areas of responsibility that do not directly fall under the purview of the SMO. For instance, the operation of food service is typically managed by the ship's culinary specialists, while management of ship maintenance falls under the engineering or deck departments, and training in fire safety is commonly overseen by the ship's safety officer or various departmental heads.
