This specification covers eight models of special purpose 6 ton, tactical, 2- and 4-wheel van semitrailers, herein referred to as semitrailers. The semitrailers are used primarily to transport and house repair parts and shop equipment (electrical or mechanical) over all types of roads and limited cross-country terrain and under extreme climate conditions.Intended Use: Semitrailers covered by this specification are military unique. The semitrailer is intended for use as a command post, a field medical station, or a large portable shop to house maintenance shop sets, tools, or other supplies for installing, maintaining, and repairing equipment in the field. With the performance needed to perform in adverse conditions, the semitrailer exceeds the criteria of a commercial type semitrailer, and is therefore considered military unique.
