Industrial wars vs peers are not won by dozens of "wunderwaffe", especially not in battleground without air superiority where killer drones and portable anti tank weapons dominate. Majority of armor losses come from drones and anti tank weapons, Russian Telegram channels are for example full of lancet kills same as Ukrainian are full of Javelins.The basic Abrams M1A2 will obliterate anything the Russians have on offer. This will be the game changer to see if Putin has the staying power to continue his aggression or amp it up. Expect a quicker solution now to end this conflict.
Challenger, Leopard II and Abrams what a lineup to take care of business.
Abrams and Leopards gonna get destroyed in same way as they get destroyed in Yemen and Syria, they gonna help for sure, but few dozens of tanks are not war winning weapons as much as Tigers were not for Germans in ww2. This is war of attrition, winner gonna be the one who outlast their opponent like in any peer vs peer industrial war.
Also tank vs tank combat is rare, only few examples so far in this war
