USAF RED HORSE is a civil engineering squadron that goes into different places to build bases or do other heavy engineering projects. RED HORSE stands for Rapid Engineering Deployable Heavy Operational Repair Squadron, Engineer
It doesn't surprise me at all that they built a gun truck, they were often deployed in front line situations building bases and facilities. Most likely they were the 555th 'Triple Nickel' Red Horse Squadron or the 554th 'Penny Short' RHS.
Some history on the two squadrons:
The 554th RED HORSE Squadron was constituted as the 554th Civil Engineering Squadron,
Heavy Repair, on 1 October 1965, and assigned to Pacific Air Forces for organization. The unit
was organized 12 October 1965 with station at Phan Rang Air Base, Vietnam. Members of the
554th and 555th, the first two RED HORSE squadrons, received training at Cannon AFB prior to
their deployment to Vietnam, and the 554th was the first to arrive in country in February 1966. Its
first major project was repair of the AM-2 runway at Phan Rang AB. In 1967, it became the first
RED HORSE unit to own and operate a concrete batch plant, constructing parking aprons. The
unit also completed numerous dormitories, dining halls, and other facilities at several bases. It was
reassigned to the 1st Civil Engineering Group in May 1967.
The 554th moved to Cam Ranh Bay AB on 15 February 1970 and then to Da Nang AB on 30
November 1971. By the end of 1971, the 554th was the only squadron remaining in the Republic
of Vietnam. It moved to U Tapao AB, Thailand, on 30 June 1972 to remove modular facilities
there. On 5 January 1976, the unit moved to its current location at Osan AB, Korea, and was
assigned to Pacific Air Forces.
The 555th, one of the original RED HORSE units and the second squadron to arrive in Vietnam,
was headquartered at Cam Ranh Bay from February 1966 to early 1970. The unit completed
much of the troop housing, roads, and utilities on the base. The 555th constructed hundreds of
buildings, maintained AM-2 runways, taxiways, and parking aprons, and sent deployed units to
several other locations to construct facilities. An 18-man unit constructed radar site facilities on Phu
Quoc Island, and the unit deployed a 50-man detachment to Nha Trang to accomplish major
construction projects at the direction of the 1st Civil Engineering Group.
The 555th was inactivated at Cam Ranh Bay on 15 December 1969.

I would be very interested to find out more information about 'No Slack' and if I were going to build a gun truck, a USAF Civil Engineering gun truck would be just perfect since that's what I was during my AF time.
