The Ukraine's Role in the Oil Sector

If you want to blow up an entire refinery, it's going to take a huge amount of ammo. The Ukrainians probably do have the capacity right now to throw a drone or two into it. But again, they're going to need dozens if not hundreds or a lot more sabotage. Pipes are easy to replace, especially in segments but if they hit them enough, they disrupt the flows the refineries shut down.
