"German 150-mm Infantry Howitzer" from Tactical and Technical Trends

The following brief description of the German 150-mm infantry howitzer (presumably the schweres Infanterie Geschütz 33, sIG 33) appeared in Tactical and Technical Trends, No. 22, April 8, 1943.

This standard infantry horse- or motor-drawn support weapon, will reportedly fire a shell weighing about 85 pounds, either HE or smoke, with a minimum range of 1,012 yards and a maximum of 5,140 yards. The ammunition is not fixed, and six types of charges are used. Either low- or high-trajectory fire can be delivered, the velocity and trajectory depending on the charge employed. Silk bags contain the powder, with a rimmed brass cartridge case to seal the breech and carry the percussion primer. Operating on impact or graze, a highly sensitive nose-percussion fuze gives either an instantaneous burst or an 0.4-second delay. While no details of a concrete-piercing shell with a base fuze are available, it would seem probable that one may be issued. The smoke shell produces a cloud 55 yards in diameter.
