ORIGINALLY, the light-weight, low-unit-ground-pressure cargo carrier called the weasel was designed primarily for snow operations; but later, as testing and development work progressed, its usefulness was extended to operations in swamps and muddy terrain, through which wheeled and high-unit-pressure vehicles could not be operated.
Many problems arose during the intensive development program that was necessary because of the need for getting the manufacture of production vehicles underway quickly.
Difficulties were experienced in steering, Mr. Churchill relates, and the tracks of early models had a tendency to throw. These and other problems discussed here by Mr. Churchill were solved, however, so that the third vehicle designed, known as the M-29, is currently in production and serving on many fronts.
