SFOD B-52 Project DELTA was formed and headquartered in Nha Trang in October 1964. Patterned after a joint Vietnamese and CIDG reconnaissance project controlled by U.S. Special Forces, codename LEAPING LENA, Project DELTA was formed to conduct the most hazardous and critical missions inside the country of South Vietnam. The organizational structure and make up of the teams was very similar to LEAPING LENA. However, unlike its predecessor, Project DELTA would prove to be one of the most successful Special Operations units in Vietnam War. In June of 1965, 5^th Special Forces Group (A), Detachment B-52 was activated to act as a controller and headquarters element for the newly formed Project DELTA and its clandestine operations. The mission of Project DELTA was to conduct special reconnaissance missions in corps areas that were designated jointly by COMUSMACV and the Vietnamese Joint Central Staff. The missions were conducted under operational control (OPCON) of a division or larger command. While the operational strength of B-52 varied and fluctuated during its history, typically it was comprised of 11 officers and 82 enlisted men from the U.S. Army Special Forces, a 105 man CIDG Nung Security Company responsible for Compound and TCC security and Bomb Damage Assessment (BDA), 20 officers and 78 enlisted men from the Vietnamese Special Forces, a 123 man CIDG Roadrunner Company and the 81^st Airborne Ranger Battalion (RVN) made up of 43 officers and 763 enlisted men. The 81^st Airborne Ranger Battalion was the reactionary force for Project DELTA.

A valuable addition to your Vietnam war military memorabilia collection.
