Who is responsible for establishing nutrition standards for meals served to military personnel during simulated and actual combat conditions?

The responsibility for establishing nutrition standards for meals served to military personnel, particularly in both simulated and actual combat conditions, lies with the Surgeon General. This role encompasses the oversight of the health and nutrition of service members, emphasizing the importance of proper nourishment for maintaining readiness and performance during operations.

The Surgeon General's office is tasked with providing guidance on dietary standards that align with the unique demands placed on military personnel, ensuring that their nutritional needs are met in various environments, including combat scenarios. This is critical for sustaining energy levels, physical performance, and overall health.

In contrast, the other options represent positions that do not possess the specific function of developing nutrition standards. The Secretary of Defense holds a broader oversight responsibility regarding defense policies, while the Chief of Naval Operations focuses on operational readiness and fleet matters. The Director of Health Services oversees health services but does not specifically set the nutrition standards for military meals.
