The 155 mm Self Propelled Gun 1C 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 (compare with US SP Howitzer Paladin which fires 6-8 rounds per minute). This self propelled gun was commissioned 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 to nine cassettes with 14 rounds in each. Loading is carried out mechanically by a cassette being lifted over to the magazine of the SP gun. Each self propelled gun is equipped with the POS 2 system for positioning and directing.

The big box at the rear is the magazine which enables the gun to fire a full magazine, 14 rounds, in 45 seconds.

The ammunition carrier can be seen behind the gun. It's a highly mobile dumper style 6 x 6 vehicle. When reloading the gun two doors on the top of the magazine (at the back of the gun) are opened and a preloaded magazine, holding 14 rounds (seven wide and two deep), is inserted.
