Just logistically speaking, imagine needing to send dozens of different types of dozens of spare parts to different sections of a thousand-mile wide front line, with different types, shapes and calibers of ammunition as well. These tanks will likely just be abandoned after they get even slightly damaged.
Yeah but you just take 50 tanks and cannibalize 10 first to broke for parts, and so on. Lmao US military hardware (and their loaded deals) are so great that even countries buying murican junk end up doing that. Like Poland and the F16
It’s a deadly version of when big companies sign up to a great deal on printers, only to realise that the ink is proprietary and extortionate.
