The M Series shelter is a lightweight, man-portable, rugged, reliable and user friendly shelter. The shelter comes in four components: Two center M Sections and two end M Caps. (End caps are two M1XBTJ's.) Each M Series shelter includes ground cover, floor, push poles and repair kit. Two Steel Pin Stake Sets are also included with each shelter but packed separately. All DRASH Shelters are operable in weather extremes from -40°C to 50°C. The M Series shelter is a versatile shelter system; it can be used as a Headquarters Complex, Hospital Ward, Treatment Facility, or indeed, as a workshop for fleet vehicles.
