Harsh operating conditions in Iraq and Afghanistan are prodding vendors to supply military clients with new solutions such as: DIGIMap software that uses a military-grade tablet computer; the Heli 21 model tank, which is a collapsible fuel tank; Deschamps Mat Systems Mobi-Mat Helipad, a polyester mesh that can be rolled out in the landing area to reduce brown-out problems; Air Covers; Expeditionary Forces Aircraft Shelter System (EFASS), re-locatable hangars; Boeing Vector tool, a database used to collect fielded aircraft technical problems.
