What I would say is,
1) How often do European tanks fight in low intensity conflict in urban setting which these soulder fired AT weapons are so effective? Lets ask why M1A2 TUSK is developed if the risk to western tanks are so mimimal? The Merkava, which is arguably even better protected than most euro/american tank in terms of urban settings are destroyed/damaged with simple shoulder AT weapons like the RGP7 or more so now like the RGP29
2) it is not like no advanced euro/american tanks have been destroyed by cheap rockets:
or have their turret blown off:
Some will claim IED, but when IED hits a tank, normally it doesn't burn through the inside, and the tank generally keep one side of the suspension and there a huge crater to one side:
3) you have to remember that most of the tanks that you see in the footage are cheap monkey models of the original. will the original fair better? I don't know, but do you judge the Abrams's effectiveness by how easy the ISIS destroyed Iraqi M1A1s?
Janes said 28 M1A1 was damanged and 5 was destroyed by ,
4) why are you comparing older T72s and T64s to modern tanks, is it a suprize that they are vulnerable to shoulder fired AT weapons of their era? Hell, it is not like the venerable RGP7 is weak, the PG-7VL we commonly see in militant videos is a single HEAT rated to >500 RHAe, the latest PG-7VR is rated to >750mm RHAe; i.e. no roof/side/deck/rear armor will be that thick. M60s, Centurions, Leopards, AMX30s of that era are also famous for brewing up.
What I am trying to say is, if the media spoon feed you information, it doesn't mean it is true, or if you cannot find information, it doesn't mean that it did not exist; and i bet you that the real events are not as romantic as the soviets wanted to create a lighter tank at the premium that it does not protect its crew well. lest we forget how much the west feared when the Iranian Centurions 105 L7; and M60 failed to penetrate the armor of Iraqi T72s. resistance to penetration is much more important than systems to deal with the penetration afterwards.
