By 1943 it was obvious to the Germans that their tank production could not keep pace with battlefield losses. One of their efforts to expedite weapons production was the conversion of old, outdated tank chassis into tank destroyers, or Jagdpanzers. Early efforts demonstrated the rushed and sometimes rough mating of a small, old tank with a large, powerful gun. The Marder series especially appeared cumbersome and top heavy. The most successful conversion was the Jagdpanzer 38(t), commonly referred to as the Hetzer.
