We are always fighting the last war, and, as Ukraine has proven, much has changed. The situation for Ukraine is dire, mostly due to a lack of manpower for the infantry. They are always on the retreat, getting holed up in cities where it is the tower blocks that become the bunkers. There are no 'big arrow' movements by the Russians, they only ever send out small groups of soldiers after lots of artillery preparation. Commonly available MANPADS mean that big tanks and planes don't go anywhere near the front. It is drone warfare. From the point of view of the Russian side, imagine if Ukraine was littered with these bunkers, all of them filled with drone operators. I would say that this would be an upgrade on what Ukraine has with the trenches they have been building in the East since 2014.

You need trenches, or something similar, if you are going to mount any kind of lasting defense. Specifically, you need a safe way to run your logistics (or in military terms: your lines of communication, which refers to your supply lines, not your phone lines). A lone bunker is incredibly difficult to resuply, relieve, or reinforce. That is the power of trenches. They give protection for when you need to move goods, people, or information. If you can cut a defensive position off from any of these, it won't stand up very long. You can still use such positions to delay. But Ukraine needs to hold territory, not delay it's loss.
