The new artillery self-propelled howitzer 2S19M2 "MSTA-S" has received several modifications compare to the previous version. The new version is equipped with a new automatic fire control system which increases the rate of fire.

Digital electronic maps are now available which significantly speeds up the terrain orientation in difficult geographical conditions and allows performing faster and more efficiently firing missions.

To reduce its visibility, the new 2S19M2 uses a set of camouflage system to reduce the thermal heat of the vehicle and increase protection against radar, thermal and optical detection of more than 1.5 times, thereby reducing the effectiveness of high-precision weapons.

The 152 mm 2S19 MSTA-S self-propelled howitzer is designed to defeat unsheltered and covered manpower, weapons and materiel to division level. The 2S19 was accepted for service with the former Soviet Army in 1989. The Russian 2S19 is very similar to the American M109 or the French AU-F1 self-propelled howitzer.

The standard 2S19 can fire at a maximum range of 25 km with standard HE-FRAG projectile and 28.9 with rocket-assisted projectile. This artillery system is also able to fire Krasnopol and Krasnopol-M precision guided munitions.
