What is an Amphibious Ready Group typically staffed with?

An Amphibious Ready Group (ARG) is typically structured around a combination of Marines and air support, making this answer the correct choice. The core purpose of an ARG is to deploy and support Marine Corps forces, particularly for amphibious assault operations and other missions that require a robust, flexible presence supported by naval assets. The Marines are trained to operate on land and are equipped for a range of missions, from combat to humanitarian assistance, while the air support component provides vital capabilities such as air cover, reconnaissance, and logistical resupply.

This combination allows the ARG to project power, sustain operations in various environments, and respond quickly to emerging threats or crises. Other options, while they may play a role in specific scenarios, do not represent the primary staffing composition of an ARG. For instance, medical personnel and supplies are essential for any military operation, but they are typically part of a broader logistical support function rather than being the primary staffing focus. Similarly, while naval artillery is a key component of naval operations, an ARG's primary mission relies heavily on the integration of Marine forces and their air support. Lastly, while allied foreign forces can enhance missions, they are not a standard component of an ARG, which is primarily an autonomous U.S. Marine and naval
