the maxxpro utilizes a crew capsule with a v-shaped hull, mounted on an international 7000 chassis. the v-hull deflects the blast of a land mine or improvised explosive device (ied) away from the vehicle to protect its occupants. because the chassis is mounted outside the armored crew capsule, there are concerns that it will likely be destroyed in the event of an ambush, leaving the soldiers inside stranded. however, according to navistar defense spokesperson roy wiley, the maxxpro "did extremely well during the tests, and we are extremely pleased." this design may prove as effective as the krauss-maffei wegmann atf dingo that uses a similar design, one which mounts an armored capsule to a unimog chassis. this design has survived a 7 kg (15 lb) land mine blast with no injuries.
