Russian MS-4

In fact, in the Manual of this mine is called "booby trap MS-4", but due to the manifold possibilities of using it should be classified as multi-min.
Mina is intended for use as booby traps, as anti-handling devices for other types of mines (anti-personnel, anti-tank, and object) as object-personnel mines as anti-vehicle mine.
However, due to the very small size (15.9 x 9.2 x 3.1 cm) and a very small explosive charge (120gr.), just as mine MC-4 can be used as booby traps, anti-handling devices and anti-tank mines. If you are using MS-4 as the object or anti-vehicle mine should it gain a more or less significant explosive charge and in such cases it may be more likely to call fuse or explosive device, because explosion of the charge itself MS-4 acts as a detonator for the main explosive charge.
To carry out the tasks entrusted to the mine it is equipped with the following sensors objectives:* The tilt sensor - triggered when tilted mines more than 20 degrees in any direction or a sudden shift of the mines in any direction;* Vibration Sensor - triggered by vibrations caused by the movement of the vehicle mines fluctuations caused by an attempt to move it, take it, attach it to anything.* Timer - triggered after a predetermined period of time within a 15 hour -360 min. The timing depends on the type and discrete set metalloelementa. Accuracy low as much depends on the ambient temperature.
Selection patterns of use mines at the expense of the rotary position switch contactor, under the cover mines, in a certain position and the installation location of the timer.
1.Rezhim object mines. Sleep timer (switch position at the middle contact).2. Mode of booby traps. Set the timer mode and mechanism of long-cocking inclined sensor (switch position the red circle) or a vibration sensor is enabled (switch position and green wavy line).3.Rezhim anti-vehicle mine. ON ON timer mode, long-cocking mechanism and the vibration sensor (switch position and green wavy line).
Access Devices mines, power supply, and the charge of the detonator when the cover is mine, located at front mines and two lockable lock box type. After the mode and run of mine (long-time charging -10-20 minutes) and close the lid becomes neobezvrezhivaemoy mine and when you open the lid explodes.
Self-destruct devices on time (except when the object mines) mine has
When used as an anti-handling device mine MS-4 is attached (glued or tied) to the anti-tank or anti-personnel mine, so that you try to remove mines from the site deminers inevitably tilt the mine, or move with some acceleration. This results in the mine explosion MS 4, which in turn leads to a main mine detonation.The same mode is used. When MS 4 is used as a booby trap. In this case, it is attached to an object, which tries to take advantage of the enemy soldiers (weapons, household items, doors and hatches, drawer, etc.).
When used as an antivehicle MS-4 is placed on or in a sufficiently powerful explosive charge, which in turn is placed under the road (rail) canvas runway. To fire a vibration sensor is quite dense ground shake when driving a car. However, the reliability of the MS-4 as such is not high, because she does not have any devices that let you adjust the time of operation and it may explode prematurely, for example, before a heavy truck or armored personnel carrier or due to other breaks ammunition on the ground. The explosion in front of a train is approaching train on 30-40 meters, which, however, does not save the train wreck because of the destruction of the railway.
The term combat operation mines limited to the ac power source, but not less than 1 month. Under normal conditions, the environment and fresh food source term battle of 3-4 months. This warranty. In reality, such mines are working for a year or more.

Housing mine is painted in matt olive green color. No markings on the body are not applied. There may be ink prints small triangle with the letters QC and process notes. Some series are mines on the side walls have metal hinges to secure the mines on the property or charge was.
