Video: Army Develops Super Structures to Safeguard Troops

Shelters protect people from the sun and wind and help them stay warm. Army shelters must do more — they shield soldiers from chemical and biological agents and the fragments from enemy mortar.

Engineers at an Army research lab in Natick, Mass., design shelters with even better capability. Their portable homes are energy-efficient, thanks to LED lighting and solar panels; easy to assemble with the use of inflatable tubes called air beams; and are invisible at night!
