Intense fighting continues in sectors of southern Ukraine. However, over recent weeks, Russia has continued to expend significant effort building defensive lines deep in rear areas, especially on the approaches to occupied Crimea.
This includes an extensive zone of defences of 9 km in length, 3.5 km north of the town Armyansk, on the narrow bridge of land connecting Crimea to the Kherson region.
These elaborate defences highlight the Russian command’s assessment that Ukrainian forces are capable of directly assaulting Crimea.
Russia continues to see maintaining control of the peninsula as a top political priority.

I assume this means that Russia is preparing to lose the area north of Crimea at some point. Let's hope that it happens rather sooner than later.
Or it's just prudent to over prepare, better safe than sorry.
