How does the GCE integrate with naval forces in an expeditionary environment?

The correct choice emphasizes the GCE's critical role in coordinating land-sea operations while leveraging naval support, which is essential for successful expeditionary forces. In an expeditionary environment, the integration of the Ground Combat Element with naval forces allows for a seamless combination of capabilities that enhances operational effectiveness.

This collaboration includes the use of naval gunfire support, amphibious assault capabilities, and transportation of troops and equipment via naval vessels. Coordinated operations ensure that ground forces can effectively respond to threats and hold territory while receiving necessary supplies and support from naval assets.

Additionally, this integration aligns with the nature of modern warfare, where joint operations among various military branches are paramount to achieving strategic objectives. Unlike the other options, which either suggest independence or a limited operational approach, the correct answer reflects a holistic view of military operations that is vital in an expeditionary context.
