Each service has introduced at least one new uniform into inventory in the last 10 years. Prior to 2002, all four military services were using the Army's Battle Dress and Desert Camouflage uniforms. However, since that time each of the services (including the Army) has developed new uniforms to address deficiencies that they identified with the existing Army uniforms. Improvements incorporated into the design of the services' new uniforms include improved visual or near-infrared capabilities for concealment and improved fabric technology. Additionally, each service introduced a service-specific flame resistant uniform in response to urgent need requests.
