Main purpose — exploration area, aqua-bottlenecking and ways to move troops. Is adopted to ’80. Taken as the base units and units of BMP-1. Installed equipment:
— Minesweeper wide grip;
— compass PAB-2A;
— navigation apparatus for TNA-3;
— unit radial observation PIR 451;
— rangefinder DSP-30;
— radio R-147 — two sets;
— termodymovoe equipment;
— portable equipment to search for mines and exploration.
The set equipment allows you to find mine at a depth of 30 cm strip of 3.6 meters, to obtain the necessary data on the slopes, cross-country, the presence of minefields and obstacles, depth, width and speed aqua obstacles in the path of the troops, the density of the bottom, ice thickness and contamination of terrain.
The device IRM «Beetle»
Housing, welded from sheets of armor, a division of 7 sections, gives protection team car from the damaging agents. The design and density of housing provided reliable car buoyancy. Bow section contains elements of hydraulics, gearboxes mine detector devices capture wide «CC.» Also, there is installed ventilation-filtration unit. Cartwright compartment and the control module is designed to accommodate the IRM team, equipment for exploration and control devices. It also has 3 machine gun and 450 rounds of ammunition, a flare gun, a thousand of ammunition for the machine gun, a dozen grenades F-1, about 15 kilograms of explosives with a set of means of detonation. Motor Division includes the engine, the system for it to work and mechanisms of the box. Aft compartment contains a rechargeable battery and is equipped with hatches to access them. The side compartments are equipped with fuel tanks. In the car roof hatches are available for members of the IWW. Rotating turret with 7.62 mm machine gun, a range of actions up to 1 kilometer, and inspection instrumentation placed the gun hatches between the driver-mechanic and service outlet of the vehicle commander.
Ability and use IRM «Beetle»
In the main, this machine operates within the IRD — engineering reconnaissance patrol. It comes department engineers with their equipment and gear. IRD can not act without the help of others in the group or the general military intelligence. During the exploration of aqua-bottlenecking using CC consider that mine detector will search only minutes while moving. Determined at the bottom cross-cut the water is determined by the movement of a car by swimming. Scanning is done bottom sonar. The number of crossings of the IRM is based on the size specified for the crossing. The flow rate is determined in the process of crossing the car. To do this, the car stopped, and reducing-increasing pace, intercept it in one place. In terms of the tachometer using the table and determine the speed flow. All results draw up an engineering reconnaissance card. The introduction of the IWW «Beetle» for intelligence aqua-bottlenecking and mine detection reduced the time intelligence is almost doubled. For self-drawing the steep-sparing or to overcome obstacles use solid rocket engines from 9M39 missiles.
The main characteristics of the IWW «Bug»:
— length of 8.22 meters;
— width of 3.15 meters;
— height of 2.4 meters;

— weight 18.04 tons;
— team of 5 people;
— engine output of 300 hp;
— Speed (land) to 52 km / h;
— speed (Water) up to 11 km / h;
— input-output (water) to 30 degrees;
— angle of 36 degrees to overcome the obstacles.
