In the period from 07 to 12 in March 2011, together with experts from the Russian Ministry of Defense and OJSC KAMAZ, special tests were carried out to determine the protective properties when exposed to damaging factors modern weapons.
The head of the Main Automobile and Armored Directorate of the Ministry of Defense of Russia, the General Director of KAMAZ OJSC, the chief designer of KAMAZ OJSC and other representatives of the defense department and the military industry attended the tests.
Measurement control devices:
Dummy Hybrid III (Hybrid III)
The following basic measuring instruments were installed in the dummy:
- load sensor in the lower part of the tibia bones of the lower extremities (on both limbs);
- acceleration sensor in the pelvic area: vertical acceleration;
- load sensor on the upper part of the neck: shear force, axial force and bending / tensile moment.
The following additional measuring devices are also used:
- five-coordinate load sensor in the lower part of the tibia bones of both lower extremities;
- five-axis load sensor in the upper part of the tibia bones of both lower extremities;
- three-axis acceleration sensors on both lower extremities, located in the middle of the tibia bones;
- one-coordinate load cell (shear force) on both thighs;
- three-axis acceleration sensors in the pelvis, chest and head;
- five-coordinate load sensor in the lumbar spine;
- six-coordinate load sensor in the upper part of the neck.
Other sensors:
- Accelerometer - bottom area under the driver
- Accelerometer - driver's footwell
- Accelerometers (4 device) - the front and rear of the roof.
In accordance with the specified parameters of the Customer (the Ministry of Defense) and the STANAG 4569, AEP55 standardization agreement, volume 2; 2 level, the mine exploded in the 6 steel body kg (trotyl) was carried out under the front left wheel.

After blasting
In accordance with the STANAG 4569 standard, when a mine explodes, its crew and passengers are exposed to shock waves, movement and deformation of local structural elements of the vehicle. The following parts of the body are considered the most vulnerable:
- Lower legs (feet / ankles / tibia);
- Thoracic and lumbar spine;
- Head / neck area;
- Gas-filled internal organs.
The car was evaluated according to the criteria of the load and the degree of damage to these parts of the body (loads on other parts of the body are considered less critical).
Also at the request of the Customer (demonstration of protection for 1 level STANAG) the following explosions were carried out:
- copies of the anti-personnel mine DM31 (without outer shell) on the front right transverse suspension arm (total weight 600 gr.)
- copies of the anti-personnel mine DM31 (without an outer shell) under the foot space on the right rear side below the bottom 470 mm from the side and at the height 200 mm from the ground (total weight 600 is gr.).
The Italian side claims that the car provides mine protection to 7 kg of TNT under any wheel and 3 kg of TNT under the bottom.
UPD.
The hatch of the LMV opens by means of increased accelerations and is independent of the internal overpressure. During the tests, this issue was discussed with the Customer, and it was confirmed that problems with overpressure for the personnel in the vehicle cabin do not exist.
Opening the roof hatch is not an automatic process; it is just the destruction of the hatch lock. It is quite possible to strengthen this lock, but none of the Customers demanded this.
In this situation, it is better to have an open exit in order to leave the cabin, because during energy absorption the cabin may be deformed, and this is a normal process.
