Retail logistics for the Army is a challenge. Moving commodities such as fuel and ammunition from the US to overseas locations is pretty much like any other industry. Rail, highway, ships, and occasionally cargo aircraft. It takes planning and attention to detail, but it’s essentially the same as civilian shipping. It’s the transfer of those commodities to the actual units on the front lines that is a challenge. In some theaters of operations, there are existing networks of improved roads that ease this challenge. In other potential theaters, not so much. And one of the Army’s great strengths since World War II has been its off-road mobility. It’s relatively easy to make tanks and armored personnel carriers off road mobile. But the trucks that must be used to support them are something of a different matter.
And so, the Army was always looking for ways to improve the mobility of its cargo trucks. One interesting approach was to use the basic structure of 1950s era earth moving equipment as the basis for a cargo or fuel tanker capable of operating in quite rugged terrain. As an experiment, a competition was held between several similar vehicles, and a handful of what came to be known as the M520 GOER family were bought, and used in Vietnam. After Vietnam began to wind down, about 1300 more were built in the early 1970s.
Pretty nifty, huh?
The problem was, while it had very good off road capability, it had attrocious on road capability, with a very low maximum speed, an unsprung suspension that was brutally jolting, and some unsavory driving characteristics.
The Army also came to realize that most of the time, it only needed decent, not excellent, off road capability. The GOER was replaced in service by the much more conventional Oshkosh HEMTT (Hemmit) 10 ton 8×8 tactical truck.
