The US doesnt even have that many ATACMS because apparently you dont need precision artillery with over 300km range if you are fighting the Taliban. So many ATACMS have expired and havent been refurbished or replaced. There havent been made any ATACMS since 2007. The ATACMS replacement just came out and has very limited availability.
Generally the West mostly has tech from the 80s and 90s or tech made to fight insurgency/taliban type threats. Only recently it started pivoting back to new weapon development for peer or near peer conflicts. The war in Ukraine and increasing threat to Taiwan has greatly accelerated that.
Thats why outside of the US, the second biggest army in NATO is Turkey and Greece is up there, in terms of tanks, artillery pieces and airplanes. Because those are the only 2 NATO countries that are prepared for a peer war.
Well Greece isnt really ready for any conflict, most of that shit is falling apart but i am pretty sure that Turkey is equally incompetent.
Turkey wants to become Great Empire again and Greece doesnt feel like sharing its stuff with Turkey. Thats how Greece ended up having as many Leopard 2 tanks as Germany.
