The Orange man being the Orange man. It looks like to me that Ukrainians are grouped together in small bunches sometimes in the 3-4 number in holes in the ground and occupy the line, basically just hide out. Ukrainians are doing a good job with drones to keep the Russians from easily dismantling the mine fields with heavier equipment. Russians are going through the lines with low counts 2-4 count and getting behind these lines but many of them expire due to the mines and drones if they use motorcycles. Russians are using less and less heavy armor, the Ukrainians basically have to walk as they get into position as Russia is able to zero in on them with vehicles. Artillery is still being used but not as much as before although near towns/cities they become more useful due to more to destroy and more troops to hit. I would expect Russian causalities to be higher due to the nature of an defender normally has the advantage but the Ukraine has a serious manpower problem. Defenses are setup to stop fast armor from coming across, but the war of attrition is not on their side in the least but Russia is now targeting the support on the back side of the line. Russia has no extended the reach of the FABs up to 100km, and their drone strategies are greatly improving at scale.
I would expect it to continue on for sometime as long if the Orange man continues to play ball with them until that time, the Ukrainians will have to move on from busification of Grandpa to busification of Grandma. It really doesn't take much skill to sit in a hole.
The Russians used a tactic of throwing meat at the Nazi during WW2, the difference here is the Ukrainians don't seem to have any plan on the back side of things. The Russians needed to slow down the Nazis to train and equipment a new army, here... there is no new army coming up - the Grandmas are the reserve I guess.
