Apparently the Ukrainians have inflicted heavy losses on some Russian force on the outskirts of Kiev using artillery fire. A couple of thoughts about this - I wonder how good the Russians are are laying their own artillery fire, given they don't appear to have much in the way of airborne assets either spotting or directing fire, hence are having only limited success against an opponent which knows the ground and manoeuvre as required? The Ukrainians in contrast may well have access to western reconnaissance data and imagery (satellite etc), giving them much more of a real-time picture.
Also, 'that' convoy appears to have dispersed off the road into the surrounding countryside (looking at those Maxar images), so fewer worries about collateral damage for the gunners.
Another thought, given the Russian forces are presumably stood-to during daylight hours, night-time harassment and interdiction artillery fire would be very useful in depriving them of sleep. This will really grind their morale.
