strike force men killed, 22 mobile strike force men wounded, and 2 carbines lost. The enemy lost 73 killed and eight small arms and assorted ammunition and supplies captured. At 1500, a new mobile strike force company was moved from Don Phuc, A-430, and relieved the company at My An. Company D, IV Corps, recommended the mobile strike force company for an award for its outstanding action against the Viet Cong battalion.
In III Corps Tactical Zone the most significant action of the quarterly period ending 31 January 1967 occurred near Camp Suoi Da, A-322, in Tay Ninh Province. On 2 November III Corps mobile strike force troops moved by air into the Suoi Da area to conduct reconnaissance missions against a known Viet Cong base area. Eight separate fights with elements of several Viet Cong regiments took place, and the mobile strike force was credited with rendering a Viet Cong battalion ineffective. Total confirmed enemy casualties were 85 killed, but another 148 were probably killed in ground action. This action was one of many in a situation that later led to the launching of Operation ATTLEBORO, up to that time the largest of the war involving conventional U.S. and Vietnamese units. (See Appendix E.)
Another significant area of mobile strike force employment was in the conduct of special operations. As part of a special operation named BLACKJACK 41C, three companies of the Nha Trang Mobile Strike Force conducted a parachute assault in the Seven Mountains region of IV Corps in May 1967. BLACKJACK 41C grew directly out of the special operation BLACKJACK 41, which had the mission of conducting unconventional warfare against the Viet Cong forces concentrated in the Seven Mountains regionï¿½a region which had long been a notorious Viet Cong stronghold. In addition to mobile strike forces, CIDG companies and a mobile guerrilla force participated in BLACKJACK 41C. The mission of BLACKJACK 41C was to exploit the intelligence gathered by the IV Corps Company D Mobile Strike Force and conduct operations to seal off Nui Giai Mountain in the Seven Mountains, denying the Viet Cong further use of it; to inflict maximum casualties on Viet Cong forces in the area; and to destroy Viet Cong command and supply installations.
The Company D Mobile Strike Force had been operating on Nui Giai Mountain since 20 April. On 9 May 1967 it received intelligence that one company from the 512th Viet Cong Battalion was operating on Nui Giai and would defend the mountain. It was decided to launch a large-scale operation to seal off Nui Giai and clear it of Viet Cong. The operation began at 0645 on 13 May with thirty-nine Special Forces troops and three companies of the 5th
