This is a unique development of Russian scientists for the army of the country. A new assault bulletproof shield was called "Zabor" ("Fence") which could be probably also listed in this post of today.
This powerful shield has a 5-class protection and can stop bullets of AKM, SVD, and even fragments of grenades, however it is rather heavy - 50 kilograms (110 lb).
As you can see it has a special corset with straps for fastening on a soldier's torso, the shield itself inserts into special grooves on the corset.
Although it is a powerful shield and can protect from almost any weapon mentioned above, it cannot be called rather comfortable.
One cannot put it on himself, putting it off is even more difficult.
