Which organization provides oversight for Navy and Marine Corps interoperability?

The Navy-Marine Corps Team (NMCT) is responsible for providing oversight for interoperability between the Navy and Marine Corps. This organization focuses on ensuring that both branches can effectively work together during operations, which is critical given their different roles and operational environments. NMCT emphasizes the integration of systems, tactics, and procedures to facilitate smooth collaboration on missions.

Considering the other choices, the Defense Acquisition University primarily focuses on training and education related to defense acquisition processes, rather than interoperability oversight. The Joint Chiefs of Staff serve as the senior military advisory body to the President and the Secretary of Defense, and while they play a role in joint operations, they do not specifically oversee Navy and Marine Corps interoperability. Lastly, the U.S. Army Corps of Engineers is involved in civil engineering and construction projects, which is not directly related to the operability of the Navy and Marine Corps. Thus, the NMCT stands out as the correct answer for this question.
