Sure ammo is coming but my point was twofold 1) lack of ammunition hampered the kherson offensive and possibly other actions. 2) the rate of use of munitions is insane and even if governments are super generous now( while holding back on Abrams and F-16s, A-10s etc) there is going to be a wall hit- once those stockpiles run out as production per year is what Ukraine can use in a few days. And some systems like stingers haven't been made since 2008. Russian production understands they are at war, the west does not. Both sides are running short but the west has a massive production advantage IF they get serious.
