soldier-friendly equipment which is light-weight, man-portable, rapidly deployable and air transportable with no tools or assembly needed. DRASH consist of no locking devices, center supports, poles and beams. DRASH is available in a wide range of sizes from small command posts to large tactical operation centers. A 5.48 m wide and 13.1 m long DRASH shelter is shown in Figure 1-5. Figure 1-5. DRASH shelter 1.3.3 Very Large Area Shelter This re-deployable, self-erect shelter is constructed from the Ably Diamond system of aluminum components [6], which facilitates modular construction of rugged, high- stability, large-area structures to precisely meet demanding applications. With clear spans of up to 35 m this flexible system is adaptable to many configurations. Erection of this structure is a fast unskilled task which does not require any handling of mechanical equipment. The fabric of this structure is fixed and tensioned simultaneously for increase ease and speed in deploying the structure as shown in Figure 1-6. The anchorage of this structure is not limited to hard foundations, concrete or prepared ground
