That’s very interesting. According to @siegecrossbow , Russia doesn’t do force on force training for large scale joint training.How much of AFU's forces in this offensive are technicals vs how much are MRAPs?
I wouldn't discount MRAP being used as ersatz wheeled IFV against Russians. Previous joint exercises between PLA and Russians have shown that Russian forces can't really handle medium combined arms brigade or SBCTs or similar wheeled medium armour formations running circles around them and striking where there they are weak. Didn't a PLA medium combined arms battalion wipe out a whole Russian mechanized infantry regiment during Vostok 2018?
Although MRAP are far from being equivalent to a Type 08, it still at least equivalent if not heavier than jeep equipped light combined arms brigades and not to be underestimated due to their speed. In fact this known Russian weakness to highly mobile units may explain their recent failure against AFU formations being used this way.
It's very complicated and not one sided Russia Stronk or Russia Joke. The Chinese military respects the Russian military for its combat experience and many of the tactics pioneered during the Syrian War but there have been concerns with the digitalization and reliability/readiness of gear at some exercises. Contrary to popular belief, large scale joint training with Russia (like Vostok) do not involve force on force combat training but attacks against static targets. In fact I do not believe the Russian military employ a professional OPFOR in either the Army or the Air Force, but I could be wrong about it. What is certain is that force on force exercises like the Stride series in Zhurihe does not have a counterpart in Russia.
