I have read a fascinating book on the hot little war US and western troops engaged in near the end of WW1 in northern Russia against the Bolshevics and in support of the White Russians. Lives were lost on both sides. I don’t know if Russia was at that time Soviet Russia or USSR, but the Bolshevics were clearly in charge of most of Russia, and the White Russians lost. If Russian memories are long, and I think they are, then I think they would consider this a case of the US in an armed encounter against their Russian forces.
Keep in mind that the “White Russians” were not a political party but instead were the people of what is now Belarus and Ukraine. That region used to be called White Russia and the name ‘Belarus’ can be translated as ‘White Russia’.
It gives some clarity as to the lingering hatred of Bolsheviks like Putin against today’s White Russians.
It also explains why Belarus is nervous about having Soviet forces on their soil again.
