PURPOSE AND SPECTRE OF APPLICATIONS
The DOZOR-B armoured personnel carrier is a 4x4 armoured fighting vehicle intended to transport personnel and various loads. The vehicle can be fitted with various light weapons, communications devices, and special equipment.
The DOZOR-B armoured personnel carrier can be efficiently used by special units of the armed forces (quick reaction forces and military police) to carry out reconnaissance, patrolling, and peace-keeping operations, as well as being used as the main transportation vehicle under combat conditions (including NBC envi-ronment).
The DOZOR-B armoured personnel carrier can fulfil its functions by day and night both on hard surface roads and in cross-country.

DOZOR-B - Armored Personnel Carrier
|
|
LAYOUT
The layout of the armoured personnel carrier is based on a motor car scheme, which makes it possible to ensure high cross-country capability while retaining ease of operation and safety of entering/leaving the vehicle. The bonnet-type layout provides the crew with an easy access to the power pack components, steering system, braking system, and air system for maintenance and repair.
The vehicle is divided into two main compartments: power pack compartment and crew compartment.
The power pack compartment occupies the front and central parts of the hull and is separated from the crew compartment by an air-tight vibration/noise-insulating bulkhead. The compartment accommodates the engine with its operation support systems, transmission, main elements of the steering system, air system, braking system, and components of the air conditioning system and heating system.
The crew compartment occupies the central and rear parts of the hull and is used for accommodating the crew, installing the assemblies required for operation of the crew, and placing various equipment, ammunition, and SPTA. The crew compartment is divided into the driving compartment, fighting compartment, and troop compartment. |
|
 |
|
Driving compartment
The driving compartment is located in the front part of the crew compartment and comprises the driver’s station fitted with armoured personnel carrier controls, and the commander’s station fitted with communications devices and navigation equipment. |
|
|
|
Fighting compartment
The fighting compartment is located in the central part of the crew compartment and comprises the gunner’s station fitted with machine gun laying and control devices.
The troop compartment is located in the rear part of the crew compartment and comprises seats for troops, periscopic vision blocks, and firing ports to enable the troops to carry out observation and to fire small arms.
The crew compartment accommodates the filtering and ventilating unit and the main components of the ventilation, heating, and air conditioning systems. |

PROTECTION
The armoured hull of the personnel carrier provides protection of the crew, troops, and internal equipment against small arms fire, anti-tank mines, and effects of the mass destruction weapons.
Dazzle painting reduces the vehicle’s visual signature and the range of its detection.
Main protection
The hull is made of armour and provides protection against 7.62 mm armour-piercing bullets.
The bottom of the armoured personnel carrier is made of armour steel in a cylindrical shape and provides protection against mines.
The armoured glass installed on the armoured personnel carrier provides protection that is identical to the protection provided by the main armour of the vehicle.
Additional protection
The design of the hull makes it possible to install additional protection array in the form of removable components that will provide protection against larger calibre bullets and more powerful mines. The level of additional protection is determined by the requirements of particular customers. |
|
|
|
Filtering and ventilating unit
The filtering and ventilating unit is intended to purify the ambient air in order to remove toxic agents, radioactive dust, and biological warfare aerosols; to feed the purified air into the crew compartment; to create overpressure in the crew compartment; and to remove firing powder gases from the crew compartment. |
|

CREW COMFORT SUPPORT SYSTEMS
Ventilation system
The ventilation system with forced air circulation is intended to supply fresh air into the crew compartment and to remove powder gases when the troops fire their small arms when the filtering and ventilating unit is switched off.
Heating system
The heating system of the liquid type provides crew comfort in cold weather due to the heating of the air in the crew compartment and blowing the heated air to the window glasses.
Air conditioning system
The air conditioning system provides crew comfort in hot weather due to the cooling or ventilation in the armoured personnel carrier.
The system ensures the following:
- cooling of air at ambient air temperatures of 20 to 55 degrees Centigrade
- ventilation of air without cooling or heating it in the entire operating temperature range of the armoured personnel carrier
|
