Designed with anti-guerilla combat in mind, Lockheed is playing on somewhat unfamiliar ground in the ground fight. Oshkosh and AM General both have troop carriers in use by the US military, while Lockheed is still more widely known for its high-tech aircraft and missile systems.

Like the other competitors, Lockheed aimed to make its slightly boxier vehicle lighter and tested it for blast-resistance.

"It can take a soldier everywhere, but can survive everything that they could survive in an MRAP," Trevor McWilliams, a former soldier whose truck was hit with an IED, said in a Lockheed promotional video.
