This is something I've noticed looking at the pro RU accounts over the past months - last year the maps covered large areas with big arrows going here and there and language describing sweeping advances and gains. Now they're reporting on this house or this street having been taken with the same language, its kind of strange. I still don't really understand why RU have chosen this hill to die on, there's how many hundreds of kilometers of front and yet they're bogged down in street fighting in one smallish city.
Makes me think that they really don't have the resources anymore for any bigger moves and that they know they're outclassed in the open so they're using the street fighting to try and even out the playing field.
