[4][5] In April 2016, with the consortium of HSW and ROSOMAK S.A., a contract was signed for the supply of eight KMO Rak systems (64 M120K mortars and 32 artillery command vehicles (AWD)) in 2017–2019.

In October 2019, another contract was signed for the supply of two KMO Rak systems (18 M120K mortars and 8 AWD) and two mortars for training at the Centrum Szkolenia Artylerii i Uzbrojenia (Artillery and Armament Training Center) in Toruń.

In 2013, as part of the MSPO exhibition, the manufacturer presented the implementation of the mortar on the chassis of the German Marder infantry fighting vehicle.

The vehicle is equipped with a digital fire control system, including a thermal camera and a laser rangefinder, so it can work effectively during the day or night.

[9][10] The Rak mortar can fire remotely as an unmanned weapon, using commands and data transmitted electronically to the vehicle's computer.
