Which aspect is NOT a function of the military sealift command?

The military sealift command primarily focuses on providing sealift capabilities to support military operations, which includes logistics support, service support, and prepositioning of equipment and supplies. Each of these functions plays a crucial role in ensuring that forces are ready and supplied as needed.

Logistics Training involves preparing personnel to efficiently manage the complex supply chains and transport logistics required during operations. Service Support encompasses various elements such as transportation of troops and equipment, and ensuring the readiness of supplies. Prepositioning is a critical function that allows for the strategic storage of military equipment and supplies at key locations to ensure rapid deployment when required.

In contrast, combat operations fall outside the realm of the military sealift command's responsibilities. While sealift operations are essential for supporting combat scenarios, the actual execution of combat operations is conducted by combat units and commands rather than the sealift command itself. Thus, this distinction clarifies that combat operations are not a function of the military sealift command.
