In September 1966, 5th Special Forces Group (ABN) established the RECONDO School in Nha Trang RVN. The three week curriculum taught techniques specific to Long Range Reconnaissance Patrolling in South Vietnam. The course was open to select US and foreign allied personnel involved in recon. Some early MAC V SOG personnel did attend the school until the Reconnaissance Team Leaders Course was opened at Camp Long Thanh in 1968. The new school was specific to classified or cross border operations.
