Jagdpanther had a cannon that was previously used on the German heavy tank used during what event?
Jagdpanther The Jagdpanther (German: "hunting panther"), SdKfz 173, was a tank destroyer built by Nazi Germany during World War II based on the chassis of the Panther tank. It entered service in 1944 during the later stages of the war on the Eastern and Western Fronts. The "Jagdpanther" combined the 8.8 cm KwK 43 cannon of the Tiger II and the armor and suspension of the Panther chassis, although it suffered from the general poor state of German ordnance production, maintenance and training in the later part of the war, which resulted in small production numbers, shortage of spare parts and poor crew readiness.
Jagdfaust The "Sondergerät" SG 500 Jagdfaust ("hunting fist") or Jägerfaust ("hunter's fist") was an experimental airborne anti-bomber recoilless rifle designed for use in the Me 163 "Komet" rocket plane by the German "Luftwaffe" during World War II.
