An ATGM launcher is fixed in the roof of the tower between the hatches of the operator and the commander. The tower houses the operator’s and commander’s workstations, equipped with surveillance devices, sights and TPU devices. In the case of the fighting compartment on the starboard side there is an ammunition pack for three ATGM containers, which is used to store and transport ATGMs inside the vehicle. The ammunition compartment consists of six locks, and each lock consists of a bracket, a spring-loaded belt with a loop and a hook. Brackets are rigidly fixed to the housing.

The troop compartment is located in the rear of the machine. It is limited to the right and left sides of the hull and is divided into two parts by an average fuel tank and a container of electrical equipment. In the airborne compartment are the jobs of crew members. At each workplace there is a device for observing the terrain when driving on combat, a loophole for firing machine guns or machine guns, fans for the extraction of powder gases and TPU devices.

The disadvantages of the BMP-2 are the low firepower and armor penetration of ATGMs, the lack of the possibility of topographic location on the ground and control of military units.

The objective of the invention is to expand the scope of the combat vehicle, increase the firepower and armor penetration of the missile weapons of the machine and improve its operational characteristics.

The problem is solved by a combat vehicle, containing a control compartment located in the bow of the vehicle, in which the driver’s and crew member’s workplaces, a power compartment with powertrain and power transmission units housed in it with systems serving them, a fighting compartment, including a tower and part of the hull behind the power compartment, an automatic gun with a machine gun paired with it, an ATGM launcher are installed on the tower, and operator and commander workstations are equipped, on the starboard side of the station, the ammunition depot of containers with ATGMs is located, and the airborne compartment located in the aft of the vehicle and equipped with crew members' workplaces, the new thing is that the combat vehicle is equipped with navigation equipment consisting of a periscope artillery compass and topographic orientation system (STO), intercoms, providing external radio and telephone communications, and an autonomous electrical unit located in the machine body, in the control department there is a service station indicator and a cartograph HUNDRED, on the roof of the hull in front of the crew member’s hatch, a satellite navigation system antenna is mounted, on the tower of the fighting compartment between the operator’s and commander’s hatches, an all-round terrain viewing device is installed, the ammunition storage of containers with ATGMs is made in the form of longitudinally fixed trays, in the front of which there are ribs, and in the back there are covers pivotally fixed on the bases of the trays and fixed with the help of eccentric locks, providing longitudinal compression of the containers to the front wall of the shell.

The combat vehicle consists of a hull (chassis) 1 and a tower 2 and is divided into four sections: control, power, combat and landing.

In the control compartment there is a workplace of the driver 3 and a crew member 4. Under the central shield of the driver there is a direction indicator 5 STO. At the workplace of crew member 4 posted cartographer 6 service station and intercom, which provides internal communication with all crew members and access to external communication. The antenna of the satellite navigation system 7 is fixed on the roof of the hull in front of the hatch of crew member 4. The power compartment is located in the right front of the hull, where the power unit 8 and power transmission 9 are located. An automatic gun 10 with a machine gun 11 paired with it is installed on the tower of the fighting compartment two launchers of ATGM 12 and hatches of the operator 13 and commander 14. Between the hatches of the operator and the commander there is an all-round viewing device 15. Inside the hull on the starboard side there is a combat station 16 containers with ATGMs, which consists of four trays 17, in front of which the ribs 18 fixed to the wall 19. The ribs 18 are designed to direct the muzzle of the anti-tank container when arming boeukladki and container retaining curb. Lids 20 are mounted at the rear of the trays, pivotally fixed to the bases 21. In the closed position, the lids are fixed with eccentric locks 22, which provide longitudinal compression of the ATGM containers to the front wall. In the airborne squad, crew members 23, 24, and 25 were equipped with tables for working with documents and intercoms providing the crew member 23 with internal communications with all crew members and access to external communications, crew 24 with internal communications with all members crew and access to external telephone communications, crew member 25 - internal communication with all crew members. On the bottom of the hull, on the left side, behind the fighting compartment, there is a 26 service station gyrometer and a radio station 27. A periscope artillery compass 28 and an autonomous power unit 29 are located on the right behind the combat station. The operation of the combat vehicle is as follows. With the help of navigation equipment, the current coordinates of the machine are constantly determined. The composition of the navigation equipment includes a periscopic artillery compass and a topographic orientation system (STO). The periscope artillery compass is designed to determine the magnetic azimuths of landmarks. STO is designed to determine and display the coordinates (X, Y) of the location of the machine, the directional angle of its longitudinal axis, the angle between the direction to the destination and the longitudinal axis of the machine (heading angle) and the distance to the destination. STO provides:

- determination and indication of the initial directional angle and the initial coordinates of the location of the machine in the starting point;

- automatic determination and indication of current coordinates, as well as the directional angle of the longitudinal axis of the machine when driving and in parking lots;

- Indication of the location of the machine on an electronic map;

- indication for the driver of the current directional angle of the machine, the angle between the direction to the destination and the longitudinal axis of the machine, as well as the distance to the destination;

- calculation of coordinates of landmarks.

The service station consists of a direction indicator 5 of the driver, a cartographer 6, an antenna of the satellite navigation system 7, and a gyrometer 26.

The heading indicator is designed to indicate the values of the current directional angle of the longitudinal axis of the machine, the current directional angle to the destination, the current heading angle and the current distance to the destination.

The cartographer is designed to control the operating modes of the service station and display navigation information. The cartographer provides:

- input of initial navigation information;

- determination of the coordinates of the machine using a satellite navigation system;

- calculation of range and heading angle to the destination;

- calculation of the coordinates of the landmark on the measured range and the angle of sight on it;

- display of the current coordinates and directional angle of the machine, as well as the directional angle and distance to the destination;

- display on an electronic map of the current location of the car, the location of the destination and direction to the destination;

- preservation at power-on of current navigation parameters.

The antenna of the satellite navigation system is designed to receive signals from satellites of navigation systems and transmit them to the cartographer.

Gyrocurric pointer is designed to determine the current directional angle of the longitudinal axis of the machine, the current coordinates of the machine and transfer this information to the cartographer and direction indicator.

STO works in three modes:

- offline mode provides the determination of the coordinates of the location of the machine according to information from the gyrometer and the speedometer sensor of the machine;

- the satellite navigation mode provides the determination of the coordinates of the location of the machine according to the signals of satellite navigation systems;

- The integrated mode provides the determination of the coordinates of the location of the machine in the autonomous system with the correction of coordinates according to information from satellite navigation systems.

Before the start of the movement, the initial values of the rectangular coordinates and the directional angle of the machine, as well as the rectangular coordinates of the destination, are entered into the STO cartographer. Own rectangular coordinates are determined by the signals of satellite navigation systems. In the absence of signals from satellite navigation systems, their own coordinates are determined according to the topographic map.

The initial directional angle of the longitudinal axis of the machine is determined using an artillery compass or electronic terrain map. The rectangular coordinates of the destination are determined by the topographic map. Using the entered own coordinates and the coordinates of the destination, the angle between the direction to the destination and the longitudinal axis of the machine (heading angle) is automatically calculated.

After the start of the movement, the determination of the navigation data in the autonomous mode takes place according to the principle of measuring the path traveled by the machine, decomposing the elementary segments of the path into increments of coordinates in accordance with the current value of the directional angle of the longitudinal axis of the machine and summing the obtained values of the increments of coordinates.

The path traveled by the machine is measured by the speedometer sensor of the machine. The speedometer sensor signals, which carry information about the distance traveled, enter the gyrometer.

Information on the directional angle of the longitudinal axis of the machine is generated in the gyrometer.

After joint processing of the angular and directional information, taking into account the initial data entered from the cartographer, the current coordinates of the machine are calculated in the gyrometer.

The calculated coordinates are transmitted from the gyrometer to the cartographer and direction indicator. In satellite navigation mode, the current coordinates of the machine are determined by the receiver of the satellite navigation system located in the cartographer. The reception of signals from navigation spacecraft and their transmission to the receiver is provided by the antenna of the satellite navigation system.

When using the integrated mode, the coordinates of a moving machine are determined similarly to the autonomous mode, while certain coordinates are corrected according to information from satellite navigation systems.

The all-round visibility device provides an optical all-around view of the terrain to crew members stationed in the fighting compartment.

The use of four third-generation ATGMs in the weapon system of the combat vehicle, which are constantly ready for combat use and capable of firing in two salvo volleys, ensures the defeat of all modern tanks, including those with active defense. To replenish the spent anti-tank missiles serves as an additional ammunition, which is located inside the machine. Launchers are loaded with anti-tank missile launchers from the combat station at short stops of the combat vehicle. The use of hinged lids with eccentric locks reduces the time required to remove a container with ATGMs from the combat station.

To power the equipment and recharge the batteries in stationary mode, the combat vehicle is equipped with an electrical unit that is installed outside the vehicle and connected to its on-board network using a cable.

Thus, the proposed technical solution allowed to expand the scope and improve the operational characteristics of the combat vehicle, increase the firepower and armor penetration of missile weapons mounted on the vehicle.
