SOV/RUS - NVU-P (řídící jednotka skupiny min)

NVU-P riadiaca jednotka skupiny mín
There are several versions of this device, the most well-known are called NVU-P (НВУ-П), VP-12 and NVU-PM VP-13.


The device is designed to control a group of up to five anti-personnel mines of different types by identifying the number and position of targets using geophones (ground shock sensors). The sixth outlet is for a tritol charge for self-destruction.
The geophone has the designation SV-20P (СВ-20П).
The target is detected at a distance typically around 120-150 meters, sighted at a distance of around 90-100 meters, and eliminated when approached at a distance of 15-20 meters.
The device reliably distinguishes human from animal movement, including walking, running and slow or fast crawling and movement on skis. The probability of error is only a fraction of a per mille.


The NVU-P device itself (to which the description refers) can be controlled (switched on/off) via a cable from the MZU device (МЗУ). The device also includes a testing and adjustment device (the logic of the device can be adapted to the local conditions of use - atypical terrain, etc., the system also has a "learning" mode). The NVU-P can also be supplemented with a device for remote radio control.
The device is standardly used with OZM-72 ("pop-up" shrapnel) and MON-50 (shrapnel directional) mines, but it can be connected to all types of mines for which MD-5M (МД-5М) electric detonators can be used - MON-100, MON-200, POZM-2, OZM-3, OZM-4, and also other mines that can be initiated electrically.


The device has a diameter of 15,5cm, height of 36cm and weight of 4,2kg. It is powered by six R20 cells. The field life (time of operation in combat mode) is up to nine months. The device will self-destruct when the mines are used up or the battery voltage drops. When controlled from the MZU device, the NVU-P device can be dismantled, in autonomous mode it cannot be removed, but it does not react to the interruption of the wires to the mines.


The NVU-PM VP-13 device is also equipped with a timer that allows the device to automatically shut down three times a day at a preset time and for a preset period of time. This allows passage through the minefield and also the replacement of consumed mines.
The NVU-PM responds to the interruption of the wire to the mines by detonating any remaining mines.


In addition, other similar systems are used in the Russian military to control groups of mines or minefields and roadblocks. They are used for temporary or permanent protection of mobile or stationary objects of special significance, covering communications and transport routes against diversionary groups, covering obstructed areas on the perimeter of military camps, and the like.

The author of the original article writes (free translation):

Citace :

The device also has another codename - Комплект "Охота" - the complete "Hunting". We explained the purpose/meaning of this device to the soldiers in simple terms - it is a mine that explodes five times in a row.


There is no way to approach it and disarm it. The seismic sensor is virtually impossible to fool. The device cannot currently be reliably found or detected by any instruments or devices - there is no means of finding mines within 150 metres yet.


Plus, the thingy is pretty sneaky. When the first soldiers explode, it's usually assumed that they've hit a normal mine and medics or comrades-in-arms go to their aid. But then a second mine goes off and hits the medics as well. If the wounded try to crawl to safety, a third mine explodes. And the OZM-72 mine explodes about a meter above the ground, so it hits both standing and crawling. So all that's left to do is lie there and bleed. You're still alive, but your chances of survival are slim. Whoever's killed immediately is actually better off.


The most ridiculous (as far as one can tell) part of the whole thing is that, for all its cruel insidiousness, the NVU-P device in no way falls under the jurisdiction of the Ottawa Convention on anti-personnel landmines. The device itself is not a mine, and even the mines attached to it are no longer mines, but warfare elements - submunitions."
