I put a preview to the animation i created to the artillery to show you how the fire is but the file doesn't include animation so you can create animation by yourself.
The 100 mm field gun M1944 (BS-3) was a Soviet 100 mm anti-tank and field gun. The gun was successfully employed in the late stages of World War II, remained in service into the 1950s, being replaced in Soviet service by the T-12 antitank gun in 1955. The BS-3 was also sold to a number of other countries and in some of these countries the gun is still in service. A number of BS-3 pieces are still stored in Russian Army arsenals.
