中華民國國徽
The design of "Blue Sky with a White Sun" was used in the unit insignia or coats of arms of some units of the United States Army that fought in World War II. The most famous unit was Merrill's Marauders (officially named the "5307th Composite Unit (Provisional)"), which has the "Blue Sky with a White Sun" as part of its badge. The usage by American troops was a result of cooperation between US and Chinese Expeditionary Force in the China Burma India Theater. Postwar US military units stationed in Taiwan, including the United States Taiwan Defense Command (USTDC) and the Military Assistance Advisory Group (MAAG), also used the design in their badges.
