The C3 is a light, 33 calibre length, 105mm towed howitzer. It can fire all NATO standard 105mm ammunition up to a range of 18.5 km and 19.5 km using HE-ER G2 and US M913 rounds. The gun is normally towed by a vehicle, but can also be lifted by helicopter and transported by air.Canada modified 96 of its 105mm C1 howitzers in 1995 to 1997 through RDM Industries of the Netherlands, primarily for equipping the Reserve Force units. RDM supplied the first modified howitzers in 1996 and fielding was complete by 1998.

The 105mm C3 is manually operated, single loaded, air cooled and used semi-fixed ammunition, and is effective in both a direct and indirect firing role. The recoil mechanism is a hydro pneumatic system that absorbs the energy of recoil by forcing oil through restricted orifices and returns the Howitzer to battery by the reaction of a compressed gas. The carriage is of the single axle type. It is equipped with a screw type traversing mechanism. The elevating mechanism is of the arc and pinion type, with a worm and a worm wheel drive.

The C3 modifications include a new, longer barrel to extend its service life, a muzzle brake, reinforced trails and the removal of shield flaps. It remains the standard light howitzer of Canadian reserve force units.The gun can be operated with a crew of five or seven, If necessary, deployment can be performed with a crew of three.
