When Lieutenant General Krueger's Sixth United States Army headquarters arrived in Australia in February 1943, the administrative functions were taken from USASOS and given to a new headquarters, United States Army Forces in the Far East (USAFFE), under MacArthur's command. This had the same name as MacArthur's old headquarters in the Philippines, but its function was different. This left USASOS with logistical responsibilities only. The new arrangement was awkward, and required considerable adjustment before it functioned properly. In September 1943, Marshall was replaced by Brigadier General James L. Frink.
