Conceptually its a shelter box, kind of the first step in survival. Looking at the deployments they've made this makes alot of sense, especially the Pakistani quake where they encountered altitude, freezing temps, and little surviving shelter. Getting people inside shelter keeps them from dying of exposure, and gives them a chance at the next level of survival. It should be very much what folks prepare for on this forum, the ability to stand up new shelter when your house is kaput in a night time earthquake, its cold and raining and your kids are shivering, their coats and clothing lost in the rubble along with grandma, Fido and the cats. Open a shelter box, set up a tent, get your kids inside, get them warm, recalibrate, then go out and begin to help others.
