This latest innovation out of DARPA was developed for use during natural disasters in order to provide relief to those caught in the aftermath. The Captive Air Amphibious Transporter is part of the Tactically Expandable Maritime Platform and can deliver supplies from container ships without the need of a port to areas where normal means of transportation are simply not an option.

The craft seen here is merely a 1/5th scale prototype, so just imagine the behemoth that could carry large shipping containers from a sea based platform to its final destination on land. The amphibious vehicle makes use of a tank like tread that is produced from many air field pontoons.
While the focus of this vehicle are clear it is hard not to imagine the possibilities for amphib assault with a GAU-19 on board. Of course air filled pontoons may not stand up so well with any countermeasure as a threat.
