The bulk of Ukraine’s best most professional forces are trapped in the Donbas where they had been massing for an attack prior to the Russian invasion. If the war does not come to a fairly quick negotiated settlement, they will be destroyed. Then Putin will impose harsher terms.
So you're saying that all of those Russian tank convoys, other armored vehicles, helicopters, etc. that have been destroyed elsewhere (i.e., outside of Donbas) were obliterated by the "second-stringers?!"
In that case, all I can say is: "Go, Team Ukraine!"

the UA 93rd may move down to reinforce.
The Ukrainians have plenty of armed forces and they are not "trapped". The Russians are having a hard time making progress in areas they should easily control. Their military has nowhere near the level of performance that many believed it did.
