I think claims of so-called monkey versions are exaggerated. Most alleged monkey export versions only differ from the domestic product slightly. For tanks, I really doubt these slight differences will involve armour content. It won't be made from solid RH steel because that will weigh >90 tonnes. It could be plates of RHA but that would be close to useless against serious anti-tank weapons. There's no sense in creating an entirely new set of ceramics just for export. It's either the exact same armour or slightly less sophisticated ceramics, laminates, and welding. The resulting difference should be minor if the armour is to work at all. The video doesn't really show Abrams being destroyed so HJ-8 effectiveness on Abrams is inconclusive. However, Abrams tank is so far from invincible, I doubt any serious military power will struggle one bit knocking hundred of Abrams out with ease so destroying them shouldn't really be a source of pride... maybe for jihadists with no training and rpgs.
Armata with new APS is much harder. Tank on tank engagements are pretty rare these days and if you know Abrams is stronger at tank vs tank owing to better firepower and sabot munitions, then only engage using drones, gunships and top attack ATGMs.
There are thousands of these youtube videos created by China haters. They've been wrong many times before and often flat out lie, so why bother with them?
