Lyman has one unique oddity...it’s where the Russian rail-line dumps off cargo for the front, and the ‘hub’ disperses ammo and supplies to the frontline by truck. If Lyman is taken and the logistics situation is terminated there....then the Russians would have to recreate a new logistics hub (probably 50 to 100 miles further south, and in a hurry).
If you were a Russian Conscript at the front and being told that food and ammo for two weeks might be a problem...then your confidence is going to be shaken.
Lyman is of importance to who?
Indications are, Lyman not as important as some, including you, are letting on or the Russians would not have just placed a garrison of roughly 500 there to garrison/hold Lyman, you think?
You are correct.
Um…I would venture to guess that Severodonetsk, Donetsk, and other cities have railway stations with more traffic than Liman (pop. 20,000 before war, essentially deserted now).
