Expeditionary Forces are military units organized to deploy quickly to a specific area, often in response to a crisis or conflict. These forces are designed for rapid mobilization and can operate independently or as part of a larger coalition. They typically include a mix of ground, air, and naval capabilities to ensure versatility in various environments. Historically, Expeditionary Forces have been used in numerous conflicts, such as the American Civil War and World War II. Their primary goal is to project military power beyond national borders, providing support for humanitarian missions, peacekeeping, or combat operations as needed.
