If you’re infantry without anti-armor weapons, it doesn’t really matter if you are facing a T-34 or an M-1, you’re phuqed. If you have Javelins, it doesn’t really matter which you are facing, you can kill it.
I guess the question is, why would Russia waste its best tanks on infantry support? Particularly when a lot of these are going to be crewed by militias and separatists anyway? And I would suspect that a lot of them are going to be used as glorified APCs anyway.
Plus it’s pretty stupid. When NATO sends fifty year old Leopards and T-55s instead of its best stuff, it’s a way of getting something into the fight and “Slava Ukraine”. When Russia pulls some crap out of a depo and sends it instead of its best stuff, it’s “Look how desperate those slaps are.”
What those like you don't understand is there are many different Anti Tank Missles (ATMs) of which the Jav is the best but most expensive.
T-55s are vulnerable to many more varied ATMs than a T-64 variant or a T-90. An old school RPG-7 would probably go through both side and the cheap old AT-4 will kill it with a single shot from any angle.
The T-55 has very old dated optics, no thermal sight, old fire control and a unstabilized gun smaller than any of the other Orc tanks that have been deployed and destroyed.
It's sad that anyone with so little knowledge of tanks and thinks a T-55 is the equivalent of a M1 feels free to spout off.
The internet is the internet.
