The M1133 Stryker MEV is the primary ambulance platform. The MEV provides the mounting capability to transport four patients on standard NATO litters, or six ambulatory patients, in addition to an ambulance team of three. The MEV provides protection for the patient and medical team and enhances the medical care in a protected environment with adequate lighting and accessible medical equipment. The MEV provides essential force health protection and supports the Army's commitment to the safety and survivability of the soldier. The first five medical variants of the Stryker rolled off the assembly line at Anniston, Ala., in late fall 2002. They were tested at Aberdeen Proving Ground, Md., and Yuma Proving Ground, Ariz., before delivery to the Stryker Brigade Combat Team at Fort Lewis, Wash., in March 2003. Fully equipping an entire Brigade Combat Team would require 17 of the vehicles.
