Rubicon has scored 500 successful strikes against Ukrainian barrel artillery. Artillery under 152/155mm now deemed under existential threat and drone range creep will eventually put all artillery under threat. Experience like this also reflects back on their own policies, probably why the Russians doesn't pursue any more new 120/122mm SPG projects anymore.
For this reason, Russian 152mm artillery work off at near maximum stand off ranges, using Krasnopol-M2 rounds, firing as few as possible, then move from site to site. The classic barrage and saturation tactics of the past now stay in the past.
Another Russian drone, the Merlin-VR, is now authorized to light up targets for Krasnopol-M2 strikes.
2S22 Bogdana gets taken out by KVN drones from the 50th Separate Brigade "Varyag", a drone specialist unit. The variation uses a Tata trailer which makes it look similar to Danish supplied Caesars in AFU service. The first strike took out the engine, and two other strikes took out the breech of the cannon. The cannon is a 155mm barrel adaption on a Hyacinth-B base and block.
Despite the range advantages of the 155mm, 155mm units are still being struck by fiberoptic FPV drones. This suggests two things that are not mutually exclusive of each other, meaning they could be both right at the same time. One is that the AFU artillery units tend to operate close to the front. The second is that Russian KVN drones operate as far as 50km and over, able to match the 155mm ranges and seek them even in their hideouts and escape places.
