United States Army Forces in the Far East
MacArthur was a well-known and experienced officer with a distinguished record in World War I, who had retired from the United States Army in 1937 and had become a defense advisor to the Philippine government. He was recalled to active duty with the United States Army in July 1941, a few months before the outbreak of the Pacific War between the United States and the Empire of Japan, to become commander of United States Army Forces in the Far East (USAFFE), uniting the Philippine and United States Armies under one command.
