Well, all I can say is this.
While Ukraine fought like NATO, but then Ukraine did not have the standard and quality of NATO, that mean whatever we do in the US or UK, Ukraine may not be able to copy exactly, which is for me, that's a good thing, because this war happen in Ukraine, and they know their backyard like it's their backyard, so they should be the one that dictate how this war is being prosecuted. I am pretty sure NATO, especially US and UK have given a lot of advice as to how they can profit from the ground (Not like making money profit, but gain upper hand) but at the end of the day, They should and better to fight the Ukrainian way.
From what I am seeing, they are doing what I predict at the beginning of the war, not sure if you had remembered when this started, we talked about what can Ukraine capitalise on the supply line during the 40 mile convoy, and I am saying they should have formed a mobile Armor brigade and do hit and run, that's what they are doing at the moment. They are attacking the center of gravity and try to push with speed and mobility, that's what get them going. That's because Russia would perfer a static set piece fight, so it's best for Ukraine not give that to the Russian. Which mean Area Denial weapon are mostly pointless in this offensive because that would limit the scope to where you get AA coverage.
If this was the US, we will own the sky and speed run the battlefield. Much like how Alexander the Great uses their cavalry, Ukraine is trying to replicate that but without Air Support, which itself is a gamble, because this would not have worked if Russia had Air Superiority.
