Final answer:
A Naval Expeditionary Logistics Group is tasked with providing logistical support to maintain forward-deployed maritime forces, with capabilities including ship-to-shore cargo movement and operational support. These groups operate globally, as mandated by Congress in the U.S. Constitution, to support defense and humanitarian missions.
Step-by-step explanation:
The mission of a Naval Expeditionary Logistics Group (NAVELSG) is to provide rapid-response logistics and support to maintain and operate forward-deployed, sustainable maritime forces. Capabilities of the NAVELSG include facilitating ship-to-shore movement of cargo, vehicles, and personnel, providing operational logistics to support the mission, and ensuring that Navy combat and support elements are supplied and ready. Projected operating areas for the NAVELSG can be anywhere around the globe where there is a need for maritime expeditionary support. These operations often encompass a wide range of environments from coastal waters to land-based operations in support of defense and humanitarian missions.
The United States Constitution states that the Congress has the power 'To provide and maintain a Navy; To make Rules for the Government and Regulation of the land and naval Forces; To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions.' This foundational mandate supports the core mission of the NAVELSG and illustrates the constitutional basis for such forces.
