On August 23, a captured German Sd.Kfz. 221 scout car was exhibited near Moscow by the Red Army.[2] Vitaliy Grachev and other GAZ engineers were permitted to inspect the vehicle; a month later Grachev arranged to have it brought to the GAZ factory for a detailed analysis.[2] Grachev was impressed by the highly faceted armour plate on the Sd.Kfz.
