The 155 mm Self-propelled Gun IC is a tracked artillery piece with splinter-protection for the crew. The gun is of Swedish design and built onto an extended MBT 103 chassis. The gun fires conventional HE shells and the range is in excess of 26 km. Rate of fire is 14 rounds in 45 seconds (cf. US SP Howitzer Paladin which fires 6-8 rounds per minute). This self-prpelled gun was commisioned in the mid-60's and is used as divisional artillery in Norrland. Ammunition handling is done from a dumper-truck with a platform and a crane accompanying the gun. The truck carries up tp nine cassettes with 14 rounds in each. Loading is carried out mechanically by a cassette being lifted over the magazine of the SP gun.

Each self-propelled gun is equipped with the POS 2 system for positioning and directing.
