The sIG 33 ("schweres Infanterie Geschütz 33") was a German 150 mm close support infantry gun used in the Second World War. The gun used was the standard German infantry heavy field cannon.

[
Panzer I chassis] .The idea for creating the sIG 33 was the realization that one could couple the immense power of artillery and give it a lot more mobility in the form of a motorized chassis. It was first mounted on a Panzer I chassis and given armored side skirts, but this was soon found to be unbalanced and the huge recoil made it very dangerous to fire because the vehicle could flip over on its side. Since the Panzer I chassis was found to be ineffective, production switched to the Panzer II, Panzer 38(t) and later the Panzer III and Panzer IV. The success of the Grille (German: "Cricket") inspired the development of the Wespe ("wasp") and Hummel ("Bumblebee") self propelled artillery vechicles which were however armed with different long barreled guns.
