The Stryker MEV is the armored ambulance version of the Stryker ICV. The rear compartment has been enlarged with vertical walls and a 25cm (10") higher roof, the rear third of which slopes downward. Two litters can be stacked two high on each side of the rear compartment, and seats for three men are found on each side of the rear compartment. This means that four litter patients or six sitting wounded can be carried, or a combination of two litter patients and three sitting wounded on the opposite side. A litter lift system capable of handling 300lb (136kg) provides easy stowage of the litter patients. The litter is placed onto a pull-out tray and locked into place, then the system moves the patient to the transport position. The medical attendant is provided with a movable seat that can be stowed in front of the medical cabinet when not needed. The MEV is fitted with the Medical Communications for Combat Casualty Care (MC4) system which provides medical staff with medical records for personnel. The MEV is unarmed, but six four-barrel M6 smoke grenade launchers are mounted on a hinged platform forward of the vehicle commander's station for self-protection. Due to budget constraints early vehicles did not have an air conditioning system installed, but subsequent testing revealed its need. Late-production vehicles were factory-equipped with air conditioning, and earlier vehicles were retrofitted with the system.

The hull bottom was modified into a double-V shape beginning in 2010 in order to help mitigate the blast effect of mines and improvised explosive devices. The double-V hull (DVH) improvements also featured enhancements to the suspension system, wider tires, a height management system, and blast-resistant seating for the infantry squad. Further upgrades--including a 450hp engine; 60,000lb (27,000kg) suspension; 910-amp alternator; and an in-vehicle network--produced the Stryker A1 variant.
