The Pak 97/38 was a German anti-tank gun used by the Wehrmacht in World War II. The gun was a combination of the barrel from the French Canon de 75 modèle 1897 fitted with a Swiss Solothurn muzzle brake and mounted on the carriage of the German 5 cm Pak 38 and could fire captured French and Polish ammunition.
Together with light weight, good mobility and sufficient anti-armor performance with a HEAT shell, it made the gun a decent anti-tank weapon. It had shortcomings, particularly its low muzzle velocity. Although this did not affect the armor-piercing characteristics of its HEAT ammunition, it meant insufficient performance when firing regular AP shells and - because of difficulties in hitting small mobile targets - its low effective range of about 500 m even with HEAT. The gun also had a quite violent recoil, especially with AP shells.
