Om Avdiivka faller kan ryssarna börja använda järnvägen.
"You touched on the supply lines. If you look closely at Avdiivka, you will see that the front line to the south (which has existed since 2014), is at a major rail line going from Luhansk to Volnovakha. In Volnovakha, it splits into two lines. One to Mariupol, and the other to Crimea through Melitopol. Obviously, it is currently unusable. But if the Russians take Avdiivka, the rail line will be usable. Which will essentially give them the ability to move trains between Russia proper (around Voronezh), all the way to Crimea, without using the Kerch bridge. On top of that, they will be able to operate trains between Melitopol, Donetsk, and Luhansk. I cannot stress how big this is. Because their capacity to transfer troops and material between ALL front lines, will increase twentyfold.
Because currently, if they want to go between Luhansk and Melitopol, they are either stuck with trucks using what are essentially backroads. Or they can use rail, but they have to go from Luhansk to Russia proper, through Rostov and Krasnodar, into Crimea, and then up to Melitopol. This train journey is essentially 10x longer."
