I still see videos of Russian drones picking off Ukrainian artillery, which indicates that artillery is still present. Lancets and FPV drones are often the killer of Ukrainian artillery these days. In one sector, even if the drone footage were published as seperate videos, the Russians took out three 2S22 Bogdanas, one Grad MLRS and one M109 Paladin in a wave of repeated FPV drone strikes. One drone isn't enough to take out a vehicle, so the drones kept hitting and hitting till the vehicle is visibly on fire, with one drone hitting the fuel tank of the 2S22 Bogdana directly. The grills used to protect the vehicles were hit by a drone first, which opened it up for subsequent fiberoptic FPV drones to take out.
The Russian armored assaults towards Shakhove fell under heavy Ukrainian drone and artillery attacks, and took casualties.
I also see frequent Krasnopol use, particularly the M2 variant, taking out strongholds, the shells directly hitting the bunkers or the shelters. These are especially used against drone control points.
I still see videos of drone and artillery strikes against mortar positions which indicates mortars are still popularly used.
Tanks are frequently used on an indirect fire mode, which let's the tank strike as far as 10km, using drones as artillery spotters. This scheme turns a tank into an SPG. But it works, with targets focused on fortifications and even on opposing drone crew. This indicates that tank crews are trained like artillery crews, kind of similar to the way German StuG crews in WW2 were originally trained as artillery crews.
There's also plenty of MLRS use. A Ukrainian bridge scouted by FPV drones and hit by Tornado-S.
Drones and glide FABs have indeed taken on a lot of the work barrel artillery used to do. On top of this, we also see more air to ground missile used by the Russians, in particular with the X-38ML and X-39 LMUR missiles. MLRS are used on positions hidden on forest patches.
But the fact that you often see black spots on the ground in many footage indicates barrel artillery is still uses frequently in general.
