Which of the following is NOT a role of the USMC?

The role of managing naval nuclear deterrence is not typically associated with the United States Marine Corps (USMC). The primary responsibilities of the USMC center around amphibious warfare, rapid deployment, and supporting naval operations. The Marines excel in seizing and defending advanced naval bases, which aligns with their core mission set. They also conduct land and air operations essential to naval campaigns, emphasizing their integration with the Navy in executing maritime strategies.

Additionally, providing close air support for ground forces highlights the Marine Corps' direct engagement in combined arms operations, ensuring that they can support infantry units in combat effectively. In contrast, the management of naval nuclear deterrence primarily falls under the purview of the United States Navy and certain elements of the Department of Defense, focused on ensuring strategic deterrence through nuclear capabilities, which is outside the traditional scope of the USMC's role.
