If not mistaken the LAW was our answer to the RPG.
There are some T80 and T90 with reactive armor according to some reports. Top of the line Russian hardware. We saw a lot of images of that stuff when they first rolled into Georgia. Since then they have dispersed into the countryside and camouflaged. No need for them anyway now, there are few Georgian tank forces and only a few fortified positions remaining.
The Russians are not using first rate equipment or forces in Georgia, except for some Spetsnaz units.
