There really will be nothing left of Donbwabwe and Luganda once the Russian army is done with them: no buildings/infrastructure (blown up by enemy artillery, or possibly own artillery if there is ever a counteroffensive), but certainly no capable men (all forcefully drafted into the army and then killed or maimed in combat).
The worst part is that both sides have the resources and will to continue fighting for quite a long time (years), unless some hard to predict event turns the tide.
