Best summary of oil infrastructure damage I have seen. Well done.
In my mind destruction of rail lines should have an equal priority. The drones, redesigned for this purpose, might be more cost effective than drones destroying fuel backing Russian front line troupes. Of course this comment is from ignorance and gut reaction.
Rail traffic by electric power has been targeted and some trains derailed some rail bridges targeted, rail ferries destroyed. So Ukraine is, no doubt, allocating resources for best ROI. I am just wishing for a quantum leap similar to there drone power to destroy oil destined to the front.
