Germans didn't just use Russian tanks but they even had dedicated facilities for repairs and doing modifications.
Not really, no. They tried, sure, particularly when they captured Kharkov but at most what they did was build unfinished hulls with what was left at the plant after the Soviets moved them to the other side of the Urals.
Also, kind of silly trying to compare T-34's with T-72, T-80's and T-90's, and even more silly when Ukraine's current industrial capacity is basically non-existantBut there are other reasons for the fact that Russian tanks, especially the T 34, were not used by the German Army:
Mere possession of a captured tank is not enough. It is useless unless continuous maintenance of the vehicles is possible, and this depends on the availability of spare parts. Aside from technical difficulties, manufacture of spare parts for the T 34 in German factories would have been possible only at the expense of a reduction in the number of German tanks turned out. For this reason the use of T 34 tanks could not be considered.
In isolated instances the German Army organized captured-tank companies using captured T 34 tanks and tried to get the needed spare parts from captured matériel. But the method was unsuccessful, and these captured-tank units were dissolved very soon. In was impossible to get enough spare parts from the matériel captured. The method also involved an irrational expenditure of effort, which was increased by the fact that maintenance itself required special experts thoroughly trained in the work and the manufacture of special repair tools.
This keeps getting thrown around but we keep seeing the Ukranians running around in T-64s, T-72M, BMP-1/2, M113, MRAPs, Hilux, Soviet vans with the odd T-72B3M or T-80BVM being the personal limo ride of one far-right commander or another.Also the Russians have left a stupid amount of working vehicles behind in Ukraine so far. Like seriously...
