|   On April 18, 1967, MACV-SOG was ordered to commence Operation DANIEL BOONE, a cross-border recon effort in Cambodia.  Both SOG and the 5th Special Forces Group had been preparing 
				to conduct cross-border operations in Cambodia. The 5th Group 
				had already established Projects B-56 Sigma and B-50 Omega, units 
				similar to SOG's SHINING BRASS organization. Operation 
				SHINING BRASS had been conducting in-country recon 
				efforts on behalf of the Field Forces, awaiting authorization to begin the Cambodian operations. Both units wanted the mission but the Joint Chiefs of Staff decided 
				in favor of MACSOG. Operational control of Sigma and Omega was eventually handed over to SOG. Project DANIEL BOONE was renamed to SALEM HOUSE in December 
				1968. SALEM HOUSE  became THOT NOT on April 1971.     |
