Not sure which artillery was used. But M777 outguns the RuZZians.
“US and Canada’s m777 artillery currently on the front line and how it outguns the Russians. Yellow is the M795E1 rounds currently being used and red are the max ranges of Russian arty.”

extended standard shell:
When fired from the M198 155mm towed howitzer (39 caliber tube) with the M203A1 propelling charge, the maximum range would be between 26.5 km (threshold) {16.46miles} and 28.5 km (objective) {17.70 miles}. Same for M-777. Longest observed shot from a M777 was 22 miles
The maximum range when fired from a Crusader type system (52 caliber tube) would be 34 km (threshold) {21.12 miles} to 36 km (objective) {22.36 miles}. Extending the range of the M795 HE projectile provides the ability to engage at an even greater distances and provides for a munitions which is compatible with current and developmental delivery systems and their associated propellants.
These extended standard shells (XM982 Excalibur GPS-guided munition) cost ~US$5,000 each. Finned and GPS guided, with a dispersion, across its entire range, of 10 meters, circular error probable of 5 m (16 ft).
2S35 Koalitsiya-SV 152mm self-propelled howitzer, range 30 - 70km. This may not be on the field yet and is so new that its production may be held up by sanctioned parts. Range of fire with standard projectile is around 30km (18.64 miles) and around 40km (24.85 miles) with rocket-assisted projectile, if were any made.
this kind of precision artillery would make it really hard for the russians to bring anything near the front lines. This is the reason for the constant background killing of tanks. They’re spotted behind the lines with drones or what not and the artillery takes them out.
Massing armor just makes it more convenient to kill more tanks and armor rapidly as happened at the river crossing.
