The Russian firearm capable of disabling an armoured vehicle that's in Ukrainian hands
Ukrainian forces continue to capture Russian military equipment, including a very powerful assault rifle.
The AS Val suppressed assault rifle is capable of penetrating 8mm of steel at a distance of 100 metres, as well as easily piercing body armour or disabling an armoured vehicle.
Many of the weapons have fallen into Ukrainian hands, having been recovered in Chernihiv by Ukrainian security services.
