No, but they haven't faced massive minefields, helicopter gunships, artillery, electronic countermeasures, airstrikes, etc when occupying Iraq or Afghanistan. Fighting guerrillas and fighting a peer army are two entirely different beasts, and we see the proof in more western tanks being lost in 2 months than USA lost in 2 decades in Iraq or Afghanistan

What, are there Russian hospitals in need of bombing? C130 can't operate if there is air defense

They had gunships in Afghanistan and US still lost, not sure I see your point here. Not to mention the Taliban didn't have close to the anti-aircraft capabilities that the Russian military has. AC-130s work fine for bombing defenseless hospitals, but against a force with radar, electronic countermeasures, anti-aircraft missiles, fighter jets, and all the other tools that a modern military has access to? I think the gunships would not be nearly as effective as you think

Russia has the best air defense in the world. C-130 is a big slow moving target. Even in Afghanistan they operated only at night.

The US lost Afghanistan where their enemies had no airsupport and old equipmemt and weren't being supplied by the global hegemon. They also lost Vietnam which they fought a much smaller less well equipped country.

So it seems you aren't aware about the $50 billion of military hardware, training, mercenaries, and aid that NATO have provided Ukraine since 2014. Are you being disingeneous for the sake of winning the argument or are you acting in good faith? I need to know whether I should continue to engage or if you're just trolling/playing dumb.
