The Ukrainian Military's Strategy to Fix Russian Units

Ukrainian military can do combined arms maneuver more at the level of platoon. Some Ukrainian brigades are almost the size of divisions, like 72nd has been fighting with Uldar. They've been expanded so much that they have a lot of units and battalions. So you could have easily taken a few brigades. I'm not saying let's not say easily because the counter arguing would be, well, but this could open up gaps, right? And it would.
