The art of armoring vehicles among russians reached the chain link nets that are now welded on the BMP-2, which is indicated by the corresponding photo with the artisanal welding of such conventional protection in field conditions.
According to the authors' idea, this product should protect the vehicle from cumulative rounds. But it can hardly help, since a cumulative grenade breaks through such a net and it will not affect the operation of its combat part in any way.
In order to counteract the cumulative warhead effectively, it must be cut, that is, the net must play the role of a knife, or it must cause premature detonation, which will reduce the impact of the cumulative jet. And the usual chain-link net or just stronger structures are incapable of this.
In particular, in 2016, russians themselves demonstrated that even light anti-tank grenade launchers ignore such decision.
But it seems that now russia has its "own atmosphere" and some russian chain-link nets producers offer them to protect armored vehicles. And not only from cumulative strikes, but also from bullets of large-caliber machine guns, the main thing is to cover a tank or different vehicle with not one, but two layers.
And although armoring with a chain link net is still not comparable to the use of a metal profile, automobile rims and parts from destroyed armored vehicles and even nets with stones on the T-72B3, the following photo deserves attention.
In it is the same BMP-2 with upgraded "protection", but also with the usual net above. Its task is to prevent the detonation of a mine dropped from a UAV or to cause the detonation at a sufficient distance. Such nets installed above the equipment at a certain height can well fulfill this task and this must be taken into account.
