SD2:155 K/17

 is a Finnish Artillery unit in Steel Division II.

Background
Finland ordered 12 French Canon de 155 L mle 1917 Schneider captured by Germany. These were used in the Super Heavy Artillery Battalion 1 ( Järeä Tykistöpatteristo 1) fighting in Karelian Isthmus. The recoil system had issues with the cold while the carriage had issues breaking. These guns were lost in June 1944 when the Soviet broke Valkeasaari sector and VT-line in Kuuterselkä and Sahakylä.
