Panzer I
The Panzerjäger I ("English: tank hunter number 1") was the first German "panzerjäger" (a self-propelled anti-tank gun, or "tank destroyer") to see service in the Second World War. All mounted the Czech Škoda-built 4,7cm KPÚV vz. 38 (German designation "4.7 cm PaK (t)") antitank gun on a converted Panzer I "Ausf. B" chassis. It was intended to counter heavy French tanks like the Char B1 "bis" that were beyond the capabilities of the 3.7 cm PaK 36 anti-tank gun and extended the life of the obsolete Panzer I chassis. A total of 202 Panzer I chassis were converted to Panzerjäger I standard in 1940–41, and were employed in the Battle of France, in the North Africa Campaign and on the Eastern Front.
