The XA-202 command vehicle is based on the XA-200 chassis, but the hull is divided into four sections – operator room, driver/commander compartment, engine room and auxiliary power unit (APU) room. The 10 kW diesel APU is installed for the operator room equipment.

The command vehicle can be fitted with a 24 m hydraulic mast. The telescopic mast is powered by the main engine hydraulic pump. It has hydraulic support legs for the vehicle and an automatic guy rope system of 5.2 m radius with hydraulic tightening system. The mast takes two people about ten minutes to deploy.

The AMOS Advanced Mortar System, which is under development, is to be integrated on the XA-200 chassis for the Finnish Army. The AMOS turret is developed by Patria Hagglunds, a new company formed by Patria and Hagglunds Vehicles of Sweden. Hagglunds are responsible for the turret and Patria Vammas for the breech-loaded 120 mm mortars. The system has a full 360 degree traverse and a high rate of fire due to the double barrel and recoil mechanism.

The AMOS twin mortar system has a direct fire capability and a digital, computerised fire control system, which can fire a variety of mortar bombs including the Strix "smart" mortar, developed by Bofors Missiles and Saab Dynamics. The top-attack Strix has a nose-mounted imaging infrared seeker for terminal guidance. Strix has a range of 5000 m.
