Discussion post / info dump for Object 477.
Appropriate post examples: Object 477 related information, directly related vehicles that are relevant to Object 477. etc…
Offtopic examples: German F-18C, M1 Thumper, general balance discussion, object 685. UNLESS related discussion of Obj.477
Research on these vehicles is quite hard, especially since I cant read Russian that well, or Ukrainian at all. So all input with sources is highly appreciated.
This post will get updated by me every now and then, but likely more frequently now at the beginning since I cant mentally get myself to cram everything I see here right now.

Protection
“The armor of the bow assembly of the tank hull had a modular structure, its dimensions were more than 1 m along the course of the projectile, much attention was paid to protecting the tank from above, as well as protecting the sides. The side armor had a five-barrier structure, and the crew hatches also had powerful multi-layer protection. An important aspect in ensuring the tank’s survival on the battlefield was active protection. Various options were considered - Arena, Rain, Drozd, Tent.”
