> Ukrainian forces have been able to take out Russian tanks using the Javelin anti-tank missile system being supplied by the U.S., and a lighter, more easily transportable missile supplied by Great Britain.
That is not true. Vast majority of tanks have been destroyed by artillery (2nd is stugna-p). You can see on the videos publish by UA. They are burning with twisted parts. Javelins don't cause this kind of damage. People with military experience would know that.
What is more, they must have a stockpile of chips in case of war (Soviet Union was the only country with aluminum cutlery - side effect of stockpiling resources for potential wars). China and other countries would give them chips quietly.
