What did the Coast Guard, established on January 28, 1915, become?

The Coast Guard, established on January 28, 1915, was formally recognized as a military service and a branch of the armed forces of the United States. This designation affirms the Coast Guard's dual role: it operates under the Department of Homeland Security during peacetime and can be transferred to the Department of the Navy during wartime. This military status allows the Coast Guard to engage in defense operations, support missions, and maintain a critical role in national security, alongside providing essential maritime safety and environmental protection. Understanding this context highlights the significance of its establishment and the evolution of its responsibilities over time, as it is integral to both civil duties and military readiness.
