The Maschinengewehrkraftwagen (Kfz.13) was based on the standard Adler Standard 6 4x4 chassis with a lightly armoured open topped body and armed with a single machine gun mounted behind a protective shield. It was issued to Reconnaissance units from 1932 and served in both Poland in 1939 and France in 1940. By 1941, however, the Kfz 13 was outdated and removed from active service and used for training purposes.
