Drozd/ERA

[Vespers War]

I have another "does anyone have any information about this" question. While looking at old Soviet prototypes, a writeup of Object 490 mentions it was supposed to have a "Shtandart" active protection system. This is a royal pain to search for online because it means Standard. I've seen mentions of it in discussion of Object 195 (the "T-95") as well, but that's all I've found. Does anyone know of any technical information about the system?

The Object 490 writeup also mentions it was intended to use Gofr ERA. Allegedly Gofr is the basis for Serbia's ERO-19 ERA on the M-84AS1, and (again allegedly) it's roughly equivalent to Relikt.
