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.
2/6
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.
3/6
The 1PN-96MT-02 sight was designed to be used to modernize the T-62 tank.
Russia is likely using it because it is now unable to produce more modern Sosna-U optics for its T-72 and T-80 tanks.
The same sight was seen on a T-72B tank receiving upgrades back in early January.
4/6
So, what is my conclusion of all this?
It seems that Russia is desperate to modernize its tanks but it can't afford to keep up, which could be due to sanctions.
This results in "hybrids" using tech designed for other tanks, crudely upgraded and sent to the frontlines.
