美軍顧問團
In April 1961, the PEO was upgraded to a Military Assistance Advisory Group (MAAG), and its members were allowed to wear uniforms within Laos. On 29 April 1961, Project Erawan morphed into Project Ekarad; despite the code name change, Lao troops still trained in Lopburi, Thailand. By June 1962, the MAAG had grown to a staff of 866, with a further 465 Filipinos from ECCOIL also employed. The MAAG was withdrawn to Thailand by October 1962 under the terms of the Geneva Agreement, becoming Deputy Chief, Joint United States Military Assistance Advisory Group Thailand. The Programs Evaluation Office would eventually be replaced by the Requirements Office of the U.S. Embassy.
