United States Marine Corps Tank Operations in Vietnam
1 October through 31 December 1965

     “In addition to air, artillery, and naval gunfire, Marine infantry units received vital combat support from the 3rd Marine Division amphibian tractor companies and tank companies. The experience of the 3rd Tank Battalion was typical of how these organizations functioned in Vietnam. The 3rd Tank Battalion Headquarters, Lieutenant Colonel States Rights Jones, Jr., and Company B arrived at Da Nang on 8 July. The battalion’s other two gun companies were already in Vietnam, attached to the infantry units. On 24 July, the battalion was assigned a general support mission, but retained operational control only of its Headquarters and Service Company. At Da Nang, Company A was in direct support of the 3rd Marines, while Company B was in direct support of the 9th Marines. Company C was attached to the 4th Marines a Chu Lai, with one platoon attached to the 3rd Battalion, 4th Marines at Phu Bai. In August, Company B, 1st Tank Battalion arrived at Chu Lai with the 7th Marines and remained in support of that regiment. Four months later Company A, 1st Tank Battalion landed with the 2nd Battalion, 1st Marines at Phu Bai.” (“U.S. Marines in Vietnam: The Landing and the Buildup – 1965”)

     “By December (1965), the III MAG tank force consisted of 65 M-48 (gun) tanks and 12 (M-67) flame tanks deployed at the three Marine enclaves (Da Nang, Phu Bai, and Chu Lai). In addition to the tanks there were 65 ONTOS from both the 1st and 3rd Anti-Tank Battalion.” (Note: Later in the War ATs came under the Command and Control of the 3d Tank Battalion)

     In the last issue of the “Sponson Box” we covered Tank Operations for the period of March, when tanks first arrived in Vietnam, through September (and Operation Starlite) of 1965. This article covers the last quarter of 1965 – from 1 October through the end of the year.

     Early in October the Marines were on the offensive but with little enemy contact. Operations RED SNAPPER and LIEN KET-10 were typical with a maximum amount of planning and coordination and a paucity of results. The Marines, however, were not discouraged and continued the offensive during November. Operation BLACK FERRET was followed by BLUE MARLIN I & II. HARVEST MOON was the last of the Marine’s big battles in 1965 and it was considered a moderate success. None of these operations included the tactical offensive deployment of Tanks which were used mainly for blocking positions, road check points, and some convoy duty in and around the Chu Lai TAOR. The 3rd Tank Battalion’s reporting on the 2 Tank Companies in the Chu Lai TAOR (B Company, 1st Tank Battalion in support of the 7th Marines and C Company, 3rd Tank in support of the 4th Marines) was rather abbreviated compared to that of Companies A & B operating in support of the 3rd and 9th Marines in the Danang Vital Area.

     The 3rd and 9th Marines operating in the Da Nang TAOR used their supporting tanks – A and B Companies, respectively, extensively in their extended patrolling offensive activities.

     “Again, during the month(s) of October, (November, and December) 1965 the majority of tank offensive operations were conducted by B Company (3d Tank Battalion) in the coastal plain southeast of Danang. On 6 October 1965 a platoon from B Company was placed in direct support of the 3d Battalion, 9th Marines operating in the center portion of the southern flank of the Danang enclave (around the Da Nang Airfield). The remainder of the company remained in direct support of the 1st Battalion, 9th Marines.” (in the area of Marble Mountain)

     On over 40 occasions during this 3 month period, tanks from B Company in support of the 9th Marine’s battalions were assigned missions in support of sweep and clear operations or patrols, reaction force, destruction of Viet Cong defensive installations, sinking sampans, providing mobile reserves, extricating friendly troops, and killing more than 50 enemy troops using machine gun and/or main armament.

     A Company tanks, supporting 3d Marine Battalions in a more stable environment around the Da Nang Airfield, saw somewhat less offensive activity but were heavily committed none-the-less. They occupied strongpoints, provided rapid reaction forces, and conducted H&I fires.

     Both C Company, 3d Tank Battalion, attached to 4th Marines’ Battalions & B Company, 1st Tank Battalion attached to 7th Marines’ Battalions, located at Chu Lai occupied strong points along the MLR, provided alert forces, participated in beach patrols, established road blocks, conducted limited sweep and clear operations, conducted H&I fires, destroyed enemy defensive positions with napalm and gun, and provide defense of the Chu Lai Airfield during the last 3 months of 1965.

Operation DAGGER THRUST


     During 1965 there was a series 5 of “DAGGER THRUST” operations conducted in 2 phases. We know there were tanks embarked (2nd Plt (Rein.), Co A, 1st TkBn) – especially during the second phase - on USS Monticello (LSD 35) and suspect that either the tanks were used in the amphibious assault role or possibly that Tankers were landed without their tanks. While this sounds a bit difficult to understand, the precedence was previously set by Lt.Col. Bodley, C.O. 3/7 when he left the tanks of the 3rd Plt, B Company, 1st Tank Battalion in the well deck of USS Point Defiance (LSD 31) landing the Tankers with their “grease guns” and .45s at Qui Nhon. He didn’t do it any differently for Operation STARLITE, or subsequently, as the SLF ground forces commander. The DAGGER THRUST operations were the follow-on operations of the Special Landing Force (SLF), however, BLT 3/7 was replaced by BLT 2/1. The Foundation is seeking information on these operations from Tankers who may have been involved.
