What does MEU consist of?

The correct answer identifies the components that make up a Marine Expeditionary Unit (MEU). A MEU is typically structured with a Command Element (CE) and a Combat Logistics Battalion (CLB). The Command Element provides command and control, intelligence, and logistics, essentially orchestrating operations and ensuring effective communication among various units. The Combat Logistics Battalion supports the unit with logistics capabilities, ensuring that the MEU remains well-supplied and operationally ready. This combination of command and logistical support is crucial for the MEU's effectiveness in rapid response and expeditionary operations.

The other choices refer to different organizational or operational constructs within the Marine Corps or other entities but do not accurately reflect the specific components of a MEU. For instance, GCE (Ground Combat Element) and ACE (Aviation Combat Element) are parts of a Marine Air Ground Task Force (MAGTF) but do not define a MEU. Similarly, NSE (Navy Support Element) and ARG (Amphibious Ready Group) are related to broader operational structures but do not encapsulate the core structure of a MEU as effectively as the CE and CLB do.
