Which of the following is NOT a focus area for the Marine Expeditionary Force's operations?

The correct answer is Cyber Security because it is not traditionally considered a primary focus area for the Marine Expeditionary Force's operations. The Marine Expeditionary Force (MEF) is primarily organized and equipped to execute amphibious assaults and support combat operations, which include both combat operations and humanitarian assistance. Forward presence refers to the strategic deployment of forces in various regions to provide reassurance and deterrence.

While cyber capabilities are increasingly important in modern military operations, the MEF's core mission does not specifically emphasize cyber security as one of its main focus areas. Instead, the MEF focuses on traditional military roles such as conducting combat operations and providing humanitarian assistance, including disaster relief and support in times of crisis, as well as maintaining a forward presence to deter adversaries and reassure allies.
