Yes, artillery is at the core of Russian military doctrine. But this only means the rest of its technology is not being used. Where is air superiority? Non-existent. Russia is afraid to put aircraft in Ukrainian sights. Where are the huge tank battles? Non-existent because the Western technology makes Swiss cheese out of even their heaviest armor. I am amazed that someone can still believe in the Russian military when despite overwhelming numbers, Russia has not been able to defend itself against its neighbor, 1/5th its size and certainly less prepared for war. You think it’s a sign of victory that Russia is now using WW2 era tanks they are pulling out of storage? If anything, that shows exactly who is running out of materiel to run the war. And NATO has plenty of munitions. I think you are confusing production and capacity. Are the production of artillery and war machines too low? Yes, and NATO is addressing those issues. However, NATO has huge reserves of munitions sitting in warehouses that it hasn’t even tapped yet. Most of the donations to Ukraine have not even been of NATO’s best stock. It just happened to be a way of clearing old munitions. In some cases, both the US and Germany were going to destroy or mothball equipment only to reroute it to Ukraine. NATO is not running out of stock, it is simply getting rid of old inventory and ramping up production on new munitions. This takes time, but they are not running out. Unlike Russia… What will Russia do next? Having their Cossacks go back to fighting on horseback when the WW2 tanks run out of parts?
The F-16s will need parts, logistics, and weapons, the pilots and ground crews will need extensive training… those jets will do nothing this year. Perhaps next year though. I agree that Ukraine is fighting with one arm tied due to NATO fears of nuclear retaliation. Is that a reasonable fear? I think so. Putin is not a sane or reasonable person. And Ukraine has shown the capability to hit Russian targets within Russian territory. If the Ukrainians were allowed to hit harder, deeper, more sensitive targets in Russia, the war would escalate – Russia would not want to be seen as beaten by its little neighbor. A shame, agree or disagree, but right now, those are the rules of war that Ukraine must abide by for continued support from NATO.
