 plus various accessories for the shelters themselves. Several of these accessories can be used to link shelters together. For transport or storage, the shelters pack down to less than 2% of its deployed size into a transport bag that can be stowed on a trailer or HMMWV. Teams of four to six can easily erect a shelter simply by pulling on the sides of the shelter and raising the shelter in designated "push points" on the shelter.


DHS Systems founder and CEO A. Jon Prusmack began building DRASH shelters more than 20 years ago after being inspired by pop-up geodesic domes he came across at trade shows. He founded the company in 1984 and DRASH shelters quickly started to be purchased by military units for use as command posts, tactical operations centers, communications centers, battalion aid stations, and forward surgical support stations.
