ww2dbaseThe 15-centimeter sIG 33 close infantry support guns, short for schweres Infanterie Geschütz 33, were the standard heavy infantry field gun in the WW2-era German army. They were designed by Rheinmetall in 1927 and were introduced into the German military in 1933, hence the designation. About 4,600 were made during the design's production life.

The 15-centimeter sIG 33 close infantry support guns were made in many variants, some of which were mounted on vehicles such as the chassis of a Panzer II, Panzer 38(t), Panzer III, and Panzer IV tanks, making them self-propelled guns.

Despite being probably rather too heavy for infantry to manhandle the 15cm sIG 33, as an infantry gun, had the advantage of packing a considerable clout (a 38kg shell is not to be sneezed at), and when fitted with the 15cm Stielgranate 42 also had considerable anti-tank potential. In fact the sIG 33, which weighed only a third of that of a conventional 15cm howitzer proved to be an outstandingly usefulness battlefield weapon even with such a relatively short range.
