It’s pretty interesting to compare the report from a year ago when Russia was still seen as some super advanced military threat with the actual performance of the Russian military in Ukraine over the past almost 3 months.
There were a lot of instances of Roman millitary in their prime performing poorly (ex Septimus Severus's wars in Caledonia) for a long period of time.
It's just 3 months of poor performance, but their potential for war is still very high.
