Which statement correctly differentiates a Carrier Strike Group from an Expeditionary Strike Group?

• A. Carrier Strike Group consists of a carrier with surface combatants and submarines, while Expeditionary Strike Group includes amphibious ships.
• B. Expeditionary Strike Group is composed only of submarines.
• C. Carrier Strike Group operates without submarines.
• D. Expeditionary Strike Group has no air-wing.

Answer: (A)

The key idea here is what the force is built around and what ships it includes. A Carrier Strike Group centers on an aircraft carrier and its air wing, with a screen of surface ships and often submarines to protect the carrier and project power at sea. An Expeditionary Strike Group, by contrast, is built around amphibious ships that carry Marines and their own air support, supported by escorts, rather than around a carrier’s fixed air wing. So the statement that correctly differentiates them is the one that says a Carrier Strike Group consists of a carrier with surface combatants and submarines, while an Expeditionary Strike Group includes amphibious ships. Why the other ideas don’t fit: Expeditionary Strike Groups are not composed only of submarines; Carrier Strike Groups are not defined by excluding submarines; and Expeditionary Strike Groups do have air power from their amphibious ships' aviation, so they’re not without an air-wing.
