What's interesting to me is the additional armor placed on Russian tanks. The armor is in the form of rather smallish rectangular packages some how fastened to the tanks surface.

It doesn't seem to have been very effective

That’s reactive armor. Those packages are supposed to contained a shaped explosive charge that detonates before the incoming projectile penetrates the armor below, and then the blast redirects the force away from the tank.

The problem is, it seems some of the tank commanders were selling the explosives in those packages, or perhaps they were never delivered. Some after-action photos shows the packages were actually filled with egg cartons instead.
