Russia has arguably the largest army of any nation. Most heavy weapons, largest stockpile, and therefore the most capacity to assault and do battle.
Iraq was a second rate army. Yet the US sent more than 500 tanks, artillery and IFVs to defeat second rate Iraq. Western airpower was decisive too.
500 combined Bradleys, HIMARS, artillery were not enough to go against the Iraqi Army in the Gulf War, let alone Russia.
I predicted this predicament, Ukraine is in, back in early 2022. Knew that the USA was not sending enough weapons to crush Russia in Ukraine.
Europe needs to ditch the USA and get nukes and re-arm. USA is an unreliable partner.
