The Palestinians blew up the one factory in the world that was still making the consumable external oil pumps the AMC V8s require to continue running. :P
Replacement operations since have been very sporadic.
As for the missiles, these tanks have APS systems that can shoot down Javelins - neutral combat experience around the world versus the Russian Arena system indicates that you need saturation attacks, preferably with heavy ATGM (which the Jav isn’t), in order to defeat Arena well enough to get a hit. The Chechens found that they had to use six or more heavy ATGM simultaneously on average to get a decent chance of one hit.
https://en.wikipedia.org/wiki/Arena_(countermeasure)#
"The Javelin can defeat Arena while in top-attack mode, due to the missile descending from too steep an angle for the system to engage properly."

Then why does Russia protest vehemently against the sale of Javelin missiles to anyone?? Your claims of Russian superiority are belied by Russia’s actual actions.
Some Americans just can’t let go of the myth that Russia is superior to us.
