More footage has been released by russian media, showing an older T-72B tank that has received upgrades recently. Let's check out some of the features...
We can see the 1PN-96MT-02 thermal sight, which further strengthens the previous analysis.
The tank seems to lack a DVE-BS weather sensor, which is needed for the fire control system to make accurate shots in different types of weather. The tank will be much less accurate.

Another feature is the new ERA protection. The "soft bag" ERA previously used has been replaced by a steel case design, which has been planned for a while.
There are possible issues with the soft bag design, such as damaging it by hitting it on buildings or vegetation.
Russian media shows T-80BVM tanks in Luhansk oblast, Ukraine. At first sight, they appear to have some modifications:
The ERA on the side skirts has been extended and the turret received a "netting" similar to that of T-90M. This appeared on recently upgraded T-72B3 tanks.

However, that's not the most interesting thing.
The tanks appear to have optics which do not match the T-80BVM's configuration. In fact, it turns out that they have the old 1G42 gunner sight paired with 1PN-96MT-02 thermals.
