Dude, thats because NATO didn't have it. NATO has a very different military doctrine. In the entire Iraq war the USA used 60K artillery shells. There were some days where Russia was using 40K a day!!! NATO and the US MIC does not like artillery because its too cheap. No money to be made selling ammo. Ukraine cannot adopt NATO doctrine fully because its based on airpower. It takes DECADES and kajillions to build it. It is also why Russia has the most advanced air defense systems on the planet, to defend against NATO. So since NATO cannot supply Ukraine to fight an artillery war, and Ukraine is unable to operate a tier 1 air force, its GAME OVER. They are now like the Germans after the Luftwaffe was wiped out. Out in the open, no where to hide with the Russians able to rain artillery, bombs, missiles and drones on them at will and observe any movement from drones and satellites. Ukraine can have some successes with drones, but Russia can double or triple that, and more anti drone systems are being deployed constantly by Russia. Like I said, tell me how ANY GOOD can come from continuing.
