I guess we weren’t prepared for a land war against Russia after all.
You spelled China wrong.
Javelins were never intended to be a primary antitank system. In a normal war, as planned anyway, these infantry ATGMs were there to protect the infantry should any enemy tanks get through all the other antitank systems, starting with air interdiction, artillery, tanks.
In Ukraine the lack of, or inadequacy of, all the other such systems made Javelin relatively more important and much more frequently used, contrary to US doctrine, but necessary due to these different circumstances.
The effect of that use of Javelins (and Stugna, NLAW, etc) was to effectively exterminate all the Russian active armored units in the first few months. The Russians have since proven incapable of resuming mobile warfare.
That is Foreign Military contract production line years. That does not count what the US and other countries already have in stock.
We probably buy and field the latest configurations of these missiles. That is probably not that same configurations the Ukrainians are getting.
