They may have targetted known fuel depots or warehouses, but I actually doubt Russia has any good intel in Ukraine anymore. They cant disrupt the ukrainian military with a bunch of predestinated drones flying 150 km/h. They are only good at targetting large infrastructure not being defended.Theirs no doubt they have targetted things of military value. Their are plenty of videos in the thread that can attest to that.
But I am also under the impression it is not always the case and I've seen some Apartment buildings attacked as well. Regardless, as you said it doesn't affect the front line. Ironically, everyone is looking for a super weapon, while its the simple things that would change the course. Shells, grenades, bullets, men and more shells. Oh yeah, and tanks.
