Crikey, no wonder Ukraine is having a go at some limited counter-offensives in other areas
My partner has been following him.
35 BTGs for one small city is amazing. The entire army at the start of the war was only 170 BTGs and they committed around 125 to the war. I've read estimates that at least 17 BTGs have ceased to exist (with survivors becoming replacements for remaining BTGs). So that 35 BTGs is about 1/3 of Russia's remaining combat power. For the Russians they are learning to concentrate forces, but they have about 60-70 BTGs left to cover a very long front.
Forbes reports that Russia is planning to strip all of its training troops to create new BTGs to throw into the fight. Their equipment quality is degrading rapidly, T-62s are replacing T-72s, T-80s, and T-90s on the front lines. Those new units will likely get whatever equipment that could be scraped together.
It will keep Russia in the fight a little longer, but the ~40 BTGs will be nowhere near as strong as the BTGs at the beginning of the war. This will leave them with nobody to train new troops. A truly desperate move.
