>>512069117 (OP)Deepstateua says the brigade in the south and I quote "simply ran out of infantry". As one does, naturally.
Anyway, I suppose that the Ukrainian command knows this spiel by now (Lysichansk, Severodonetsk, Bakhmut, Avdeevka, Velika Novosilka, etc) and chose to prematurely depriorotize this frontline which effectively reduced their supplies and reinforcements to an absolute minimum.
HOWEVER, the ever watchful eye of Mordor spotted this carelessness and instead of doing the same ol' same ol' as the last 5 times decided to slip a few scouts in and after one (1) successful ambush the Ukies now don't dare cross the main street anymore. The main troopers then moved up and suddenly we're in the Pokrovsk arc that was scheduled for fall.
The only offensive operations the Ukrainians are doing currently are being conducted in Sumy in that tiny buffer zone the Russians carved out. They retook 2 or 3 villages, I believe. This is also where most of the Russian special units (vdv, marines) are located.
My guess is that the Ukrainian high command would rather spend time trying to destroy them than random Russian soldiers and as such priorotizes bumfuck places in Sumy over a logistics hub such as Pokrovsk in search of the ever-elusive great orc, the uruk-hai.
