First I have almost 40 years military service including gulf 1-2 iraq and Afghanistan so take your assumptions spoken as fact and …..
As to losses I am speculating, you on the other hand seem to know both Ukrainian and Russian losses, that is quite an accomplishment
As to knowledge 0 Americans were “mobilized “ we are a voluntary service, and “war” whoa that kind of talk will get you sent to a gulag or the front line don’t you know it is a SMO
Then there is losses, America lost under 2500 service members in 20 years in our “SMO”, well there’s that
If you have experience then you are intellectually dishonest or trolling.
I don’t know exact figures for Russian and Ukrainian losses but it is not hard to guess that Ukrainian is ten to twenty times higher.
And the Americans were mobilized for Afghanistan, don’t tell me that the reserved weren’t called.
Regarding losses in Afghanistan, imagine if they had a million strong regular army combined with the Air Force and advanced air defenses. You comparison is way off.
Your experience is needed in Ukraine. Go put your $$$ where your mouth is.
