7.5 cm KwK 37
From Infogalactic: the planetary knowledge core
The 7.5 cm KwK 37 L/24 (7.5 cm Kampfwagenkanone 37 L/24) was a shot-barreled, howitzer-like German 75 mm tank gun used during World War II, primarily as the chief weapon of the early Panzer IV tanks and early StuG III assault guns.
It was designed as a close-support artillery gun firing a high-explosive shell (hence the relatively short barrel), but was also effective against the early war tanks. Starting from March 1942,[1] new variants of the Panzer IV and StuG III had their main armament upgraded to the new longer-barreled 7.5 cm KwK 40. When older Panzer IVs were upgunned, their former KwK 37 guns were reused to arm later Panzer III tanks and other infantry support vehicles.
