Now that there are once again news about Russia's losses in Ukraine I checked how the military graveyard in Kaliningrad I passed on my way to Baltic 1200 km brevet in 2018 is faring today. I don't know if graveyard shares other uses, but maybe half a km^2 added since then. https://livingatlas.arcgis.com/wayback/#mapCenter=20.55196%2C54.81110%2C15&mode=explore&active=64001
