Infantry fighting vehicles

• BMP (Ob'yekt 764) – The original main prototype of the BMP-1 was developed by the design bureau of the Chelyabinsk Tractor Works (ChTZ) and built in 1965. In comparison with Ob'yekt 765Sp1, Ob'yekt 764 was 4 mm higher, had a maximum swimming speed of 10 km/h, a lower maximum range (550 km on road) and a reduced number of firing ports for its passenger's armament (six). The vehicle had a curved shock-absorber behind the first road wheel and the rear fender and two tool stowage boxes on the fenders. To start production of the new vehicle, the design of the fighting and troop compartments were improved. Unlike the BMP-1, Ob'yekt 764 used a waterjet for swimming, which was removed to save space inside the vehicle. Ob'yekt 764 also had a larger main fuel tank, while the BMP-1 had the main fuel tank reduced in size and partially placed under the troop compartment.^[1]
  • Ob'yekt 765 – An improved Ob'yekt 764.
  • Ob'yekt 765 was fitted with an active location system for its eight passengers. It was developed in the mid-1960s. Its turret was moved to the rear of the hull. It was also fitted with three additional 7.62 mm PKT general-purpose machine guns in ball mounts in the middle of the hull. Three prototypes were built.^[2]

    

    • BMP (Ob'yekt 765Sp1) (Sp stands for spetsifikatsiya – specification) – An early type with a shorter nose section and a larger angled plate at the top of the hull line. The two tool stowage boxes on the fenders were removed. The swim vanes were modified by reducing the number of vanes from seven to four and the fender profile was raised nearer to the horizontal. The fume extraction ports on the hull roof to the rear of the turret were moved outwards and reoriented to point toward the rear of the vehicle. The single torsion bar used to spring the rear roof troop hatches was replaced by a twin torsion bar system. The firing ports on the side were moved up into the armor plate, giving the weapons used in the ports a higher degree of elevation. The vehicle weighs 12.6 tonnes. It was built from 1966 to 1969. It is sometimes incorrectly known as the BMP-A by some Western sources. NATO gave it the designation BMP Model 1966.^[1][3]
      • BMP-1 (Ob'yekt 765Sp2) – The standard production version weighs 13 tonnes. It was built from 1969 to 1973. Vehicles produced from the mid-1970s had a higher hull with more space inside as well as a different shaped nose section which also made it 20 cm longer, giving it an improved swimming capability. The triangular air intake behind the turret was replaced by a circular telescopic snorkel which was raised when the vehicle was afloat. The roof hatches were also slightly rearranged, the air intake located to the front left side of the driver's station was removed and the NBC sensor cover was moved inwards, closer to the turret. To the left of the turret was a prominent NBC filter cover and the PKM port was redesigned. NATO gave it the designation BMP Model 1970.^[1]
        • BMP-1 (Ob'yekt 765Sp2) was equipped with a stabilization system for its 73 mm main gun, a semi-automatic guidance for the 9S428 anti-tank-guided-missile (ATGM) launcher, an improved NBC system, a more powerful engine, an improved automatic loader and improved night vision devices.^[1]
          • BMP-1 (Ob'yekt 765Sp3) – A slightly improved and 200 kg heavier version of Ob'yekt 765Sp2. Unlike its predecessors it had OG-15V HE-Frag rounds in its ammunition load. It was fitted with the new 1PN22M2 sight (with an additional tangent scale OG to be used with HE-Frags OG-15V rounds) instead of the 1PN22M1 sight as well as with a traffic signal system (six marker lights and one stop light). The M3 autoloader was removed. It was built from 1973 to 1979. NATO gave it the designation BMP M1976.^[4]
            • BMP-1S – The experimental prototype was equipped with the AV-1 device at the commander's station for target laser designation and for damaging enemy optics. Developed and tested in the 1970s, ammunition for the ATGM launcher was reduced from four to two 9M14Ms, as was the number of passengers (seven instead of eight).
            • BMP-1 (Ob'yekt 765Sp8) – This variant was additionally armed with a 30 mm AGS-17 "Plamya" automatic grenade launcher for which it carried 290 rounds. A large number of BMP-1 (Ob'yekts 765Sp1-765Sp3) IFVs were upgraded to this model during preventive and major repairs. Such IFVs carried up to seven troopers instead of eight. In Western sources they are sometimes called the "BMP-1G" but this is not an official Soviet designation. NATO gave it the name BMP M1979/1^[2]
            • BMP-1 – Fitted with six 81 mm 902V "Tucha" smoke grenade launchers at the rear of the turret. Western sources often call it the BMP-1M but this is not an official Soviet designation.^[3]
              • BMP-1 – Modernized by the Belarusian 140th Repair Workshop from Barysaw in Belarus during major repairs between the 1970s and 2000s (decade). The modernization package included the pintle-mounted 9P135M-1 ATGM launcher capable of firing SACLOS guided 9M113 "Konkurs" (AT-5 Spandrel), 9M113M "Konkurs-M" (AT-5B Spandrel B), 9M111 "Fagot" (AT-4 Spigot) and 9M111-2 "Fagot" (AT-4B Spigot B) ATGMs as well as a new electronic pulsed infrared jam-resistant weapon system.

                

            • BMP-1P (Ob'yekt 765Sp4) – The first serious modernization of the BMP-1; it was developed in the middle of the 1970s after an analysis of BMP-1 combat use during the 1973 Yom Kippur War and during the Angolan Civil War three years later. Firepower was enhanced by adding the pintle-mounted 9P135M launcher with a semi-automatic control capable of firing SACLOS guided 9M113 "Konkurs" (AT-5 Spandrel) and 9M113M "Konkurs-M" (AT-5B Spandrel B) ATGMs which increased armor penetration and extended weapon range. The new ATGM launchers were somewhat difficult to operate since the gunner had to stand in the open hatch on top of the turret to use the weapons, exposing himself to hostile fire and in NBC conditions destroying whatever value the BMP-1P's NBC protection suite gave. The Malyutka loading hatch was usually welded shut and the mount was removed. A special NBC protection covering was placed on the inside and outside of the turret, hull, engine compartment upper access hatch, commander's and driver's hatches as well as under the driver's station. A new fire-extinguisher system for protection against napalm was installed after an analysis of armored fighting vehicle (AFV) usage during the Vietnam War. There is an additional machine gun firing port on the left side of the hull and at the front of the turret, increasing the number of firing ports from seven to nine. For protection against air attacks, two 9M32M "Strela-2M" (SA-7b "Grail" Mod 1) or 9M313 Igla-1 (SA-16 Gimlet) missiles of corresponding performance were added instead of the previous 9M32 "Strela-2", but sometimes they were replaced by an RPG-7 anti-tank rocket propelled grenade launcher. The BMP-1P weighs 13.4 tonnes. It was built from 1979 to 1983. NATO gave it the designation BMP M1981^[2][3][4]
              • BMP-1P (Ob'yekt 765Sp5) – It was a late production model fitted with six 81 mm 902V "Tucha" smoke grenade launchers at the rear of the turret and additional kovriki turret armor (some vehicles may lack either the grenade launchers or the additional turret armor). Some vehicles were equipped with a track-width KMT-10 mine plow. In Western sources, BMP-1Ps that were fitted with smoke grenade launchers are often called BMP-1PM but this is not an official Soviet designation. Sometimes a BMP-1P fitted with the KMT-10 is called the BMP-1PM1 and the BMP-1P fitted with additional kovriki turret armor is called the BMP-1PM2 but those are not official Soviet designations.^[2][3]
                • BMP-1PG (G stands for granatomyot – grenade launcher) is a BMP-1P armed additionally with an AGS-17 "Plamya"automatic grenade launcher on the left hand side of the top of the turret for which it carries 290 grenades. The BMP-1PG was inspired by self-made field modifications. Some crews participating in the Soviet–Afghan War welded a grenade launcher to the top of the turret in order to compensate for the quite low fragmentation effect of the OG15V HE-Frag round used by the main gun. The vehicle weighs 13.6 tonnes and can carry up to seven soldiers instead of the usual eight. A new 9K34 "Strela-3" man-portable air-defense system, was carried inside the troop compartment. A short production run took place at the end of the 1970s. The vehicle entered service with the Soviet Army but many were exported. NATO gave it the designation BMP M1979/2.^[3]
                • BMP-1PG (G stands for granatomyot – grenade launcher) – Modernization was carried out by the Kurgan Engineering Works. There are two variants. The first has tracks and drive sprockets from the BMP-2. The second is the same as the first except for minor chassis improvements and flotation sides-skirts/mudguards from the BMP-2 (many BMP-1Ps were converted into the second variant. They were also fitted with the whole fighting compartment from the BMP-2). The BMP-1PG is considered by the Russian Army, to be the same as the BMP-2, in terms of efficiency. Some BMP-1Ps were reengineered into BMP-1PGs by tank repair plants during scheduled major repairs, some – by the main manufacturer "Kurganmashzavod".^[2][5]
            • BMP-1D (D stands for "desantnaya" – assault) – This vehicle is a modernized BMP-1 built in 1982 for Soviet assault battalions serving in Afghanistan. It is often known as the "Afghan" variant. It has 5–6 mm thick appliqué steel armor on the sides of the hull as well as five plates per side covering the suspension and additional armor under the commander's and driver's seats for protection against mines. Because of this modification, the side armor of the BMP-1D is able to withstand 12.7 mm armor-piercing rounds fired by the DShK and Browning M2 heavy machine guns used by the Afghan Mujahideen, which can penetrate the side armor of the standard BMP-1, as well as larger artillery shell fragments. The additional armor has holes cut out to allow the transported infantry to use their small arms through the firing ports. Additional firing ports were added into the top hatches of the troop compartment and a stowage box was placed on the roof at the rear of the hull (some vehicles did not have it). The use of appliqué armor increased the ground pressure to 0.65 kg/cm², decreased the maximum range to 500 km and jeopardized the amphibious ability. The 9S428 ATGM launcher was often replaced by an AGS-17 "Plamya" automatic grenade launcher in field conditions.^[1][3][6][7]
  • Ob'yekt 768 – It was an experimental IFV utilizing parts of the BMP-1 developed and built in 1972. A new two-man turret armed with a 73 mm "Zarnitsa" semi-automatic smoothbore gun and a 12.7 mm coaxial heavy machine gun, was installed. The original design included a small rotating turret on top of the commander's hatch armed with a 7.62 mm PKT general-purpose machine gun but it was not included in the prototype. It was also armed with a pintle-mounted ATGM launcher capable of firing SACLOS guided 9M113 "Konkurs" (AT-5 Spandrel) and 9M113M "Konkurs-M" (AT-5B Spandrel) ATGMs. It carried 40 rounds for the main gun, 500 rounds for the coaxial machine gun and 4 ATGMs. Ob'yekt 768 had a significantly modified nose section and strengthened suspension with an additional road wheel. The track unit was equipped with hydrodynamic grills to increase swimming traction performance but it was decided to remove them because of the damage from stones. It weighed 13.6 tonnes and had a crew of three men (+ 7 troopers). The prototype is preserved at the Kubinka Tank Museum.^[2]
    • Ob'yekt 769 – An experimental IFV based on an Ob'yekt 768 chassis and built in 1972. It was fitted with a new turret armed with a 30 mm 2A42 autocannon and a 7.62 mm PKT coaxial machine gun. A second PKT was installed in a small rotatable turret on top of the hull. It was also armed with a pintle-mounted ATGM launcher capable of firing SACLOS guided 9M113 "Konkurs" (AT-5 Spandrel) and 9M113M "Konkurs-M" (AT-5B Spandrel) ATGMs. It carried 500 rounds for the main gun, 2000 rounds for the machine guns and four ATGMs. The track unit, with hydrodynamic grills, was used for swimming. It was fitted with a diesel engine developing 321 hp (239 kW), weighed 13.8 tonnes and had a crew of three (plus 7 troopers). The turret developed for the Ob'yekt 769 was later slightly improved and installed on the BMP-2. The prototype is preserved at the Kubinka Tank Museum.^[2]
  • Ob'yekt 680 was an experimental IFV utilizing parts of the BMP-1. It was developed and built in 1972. It weighed 13 tonnes and had a crew of 3 (plus 7 troopers). It was armed with a 30 mm 2A38 autocannon and a PKT machine gun fitted into a completely new turret. A second PKT machine gun was installed on top of the commander's hatch. It carried 500 rounds for the main gun and 4000 rounds for the machine guns. This prototype is preserved at the Kubinka Tank Museum.^[2]

    

  • Ob'yekt 675 was an experimental IFV that had enhanced combat characteristics and utilized parts of the BMP-1; it was tested in 1974. The two-man turret was armed with a 30 mm 2A42 autocannon with a two-plane stabilization system and one 7.62 mm PKT coaxial machine gun. A second machine gun was fitted on top of the commander's hatch. The vehicle carried 500 rounds for the main gun and 2000 rounds for the machine guns. It was also armed with a pintle-mounted 9P135M-1 ATGM launcher capable of firing a SACLOS guided 9M113 "Konkurs" (AT-5 Spandrel) and a 9M113M "Konkurs-M" (AT-5B Spandrel B) as well as a 9M111 "Fagot" (AT-4 Spigot) ATGM and a 9M111-2 "Fagot" (AT-4B Spigot B) ATGM. The vehicle could carry either four "Konkurs" ATGMs or six "Fagot" ATGMs. ATGM guidance equipment is located on the top of the turret and is separated from the ATGM launcher. The IFV weighed 13.6 tonnes and had a crew of 3 (+ 7 troopers).^[2]
  • Ob'yekt 681 – An experimental IFV also utilizing parts of the BMP-1 IFV – it was developed and built in 1977. It weighed 13.6 tonnes and had a crew of 3 (+ 7 troopers). It was armed with a 73 mm "Zarnitsa" semi-automatic smooth-bore gun with a two-plane stabilization system, a 12.7 mm NVST coaxial heavy machine gun, a 7.62 mm PKT machine gun and a 9P135M ATGM launcher. It carried 40 rounds for the main gun, 500 rounds for the coaxial machine gun and 2400 rounds for the machine gun.^[2]
  • BMP-2 (Ob'yekt 675) – An IFV with enhanced fighting qualities based on the BMP-1 and fitted with a new two-man turret armed with a 30 mm 2A42 autocannon.

Command and staff

• BMP-1K (Ob'yekt 773) (K stands for komandirskaya – command) – Command variant of the BMP-1 for motorized rifle regiments, developed in 1972. One of the most common BMP-1 conversions. Production started in 1973. Standard armament was preserved. The troop compartment was redesigned to accommodate field tables and map boards. There is seating space for three officers. It has an additional antenna, R-123M and R-111 radios and a GPK-69 navigation system. All firing ports except for the one in the left rear door and periscopes were blocked (all machine gun firing ports were welded shut along with all firing ports on the right hand side of the hull). Some are equipped with the GLONASS navigation system. NATO gave it the designation BMP M1974. It has three sub variants:^[1][3][4]
  • BMP-1K1 – Platoon command variant of BMP-1 with two R-123M radios.

The firing ports and periscopes on the right of the vehicle are blocked. Some IFVs are equipped with the GLONASS navigation system. Vehicles that are based on Ob'yekt 765Sp5 are sometimes called, in Western sources, "BMP-1PKM" or "BMP-1PMK" but those are not official Soviet designations. It has three sub-versions:^[3]
  • BMP-1PK1 – Platoon command variant of the BMP-1P.
  • BMP-1PK2 – Company command variant of the BMP-1P.
  • BMP-1PK3 – Battalion command variant of the BMP-1P with telescopic mast mounted on the right side at the rear of the vehicle.

• BMP-1KSh (Ob'yekt 774, 9S743) (KSh stands for komandno-shtabnaya – command and staff) – Command and staff variant of the BMP-1 for motorized rifle and tank regiments with a TNA-3 gyroscopic navigation device, two R-111, one R-123MT and one R-130M additional radios as well as telegraph and telephone equipment. The armament was replaced by the AMU "Hawkeye" 10 m long telescopic mast and the turret was fixed. It also had a tubular case for the AMU "Hawkeye" antenna parts on the right rear of the vehicle, an AB-1P/30 1 kW box-shaped portable petrol-electric generator set at the center of the rear part of the hull's roof instead of two roof hatches (two roof hatches immediately behind the turret remain) and four elevatable whip antennas at the rear (two on the left and two on the right). The vehicle weighs 13 tonnes and has a crew of 3 + 4. It is armed with one 7.62 mm PKT machine gun. It officially entered service with the Soviet Army in 1972, production did not start until 1976. It saw service in Afghanistan and Chechnya. There were three variants of the BMP-1KSh, one being the "Potok"- 2, each had different additional equipment (including R-137 or R-140 or R-45 radios). NATO gave it the designation BMP M1978.^[4][8]
  • BMP-1KShM – Modernization of the BMP-1KSh, new improved navigational and radio equipment was installed. Visual differences between the BMP-1KSh and the BMP-1KShM are insignificant. It was widely used during counter-terrorism operations in Chechnya.^[2]
    • MP-31 (BMP-76) – Modification of the BMP-1KShM fitted with a more powerful 5 kW electric generator, additional antennae in the rear part of the hull as well as a gearbox installed on the left hand side, near the generator. It is used for artillery fire control. It is part of the PASUV "Manyevr" automated field air defense command set.^[3]

Combat reconnaissance

• BRM-1 (Ob'yekt 676) – At the end of the 1960s, the Soviet Army started looking for a reconnaissance vehicle suited to the modern battlefield that could be fitted with extensive electronic reconnaissance equipment. Existing reconnaissance vehicles in the Soviet Army, such as the PT-76 amphibious light tank and the BRDM-2 amphibious armored scout car, were only equipped with standard vision devices. The BMP-1 was chosen as the platform for the new reconnaissance vehicle because it had an amphibious capability, good maneuverability, a powerful armament, a spacious hull and an NBC protection system. The development of the BMP-1-based reconnaissance vehicle began in the Chelyabinsk Tractor Works (ChTZ) in the 1960s and 1970s. It was later continued by the Kurgan Engineering Works (KMZ). As a result of that the new BRM-1 officially entered service with the Soviet Army in 1972, production began in 1973 when the first BRM-1s were passed to reconnaissance subunits. It was fitted with an extra-wide, low-profile, two-man turret which was moved to the rear of the hull and without the M3 autoloader and the 9S428 ATGM launcher (although some vehicles did have the ATGM launcher). There were also two small roof hatches, instead of four in the rear part of the hull. A PSNR-5K (1RL-133-1) "Tall Mike" ground surveillance radar which can be extended over the roof of the turret from a rearward-opening hatch in the roof of the turret, (the BRM-1 of the first series did not have ground surveillance radar), a 1D8 laser rangefinder, a TNA-1 or TNA-3 gyroscopic navigation device with coordinates recorder and additional R-123M, R-130M, R-148 and R-014D radios are all fitted. Radio range is up to 50 km with the use of a standard 4 m whip antenna and up to 300 km with the use of the radio mast transported on the rear of the hull. The PSNR-5K "Tall Mike" radar, which is operated by the commander, has two modes – terrain survey and target tracking. It can detect vehicles up to 7000 meters and personnel up to 2000 meters away and can be retracted into the turret when not in use. The doppler radar for range calculations was installed from 1993 onwards. One vehicle was assigned to each recce company of a motorized rifle, tank or artillery unit. The crew was increased from 3 to 6 (commander and gunner who occupy the turret, driver and navigator who occupy the nose section of the hull and two observers who occupy the rear part of the hull). Some vehicles were fitted with a bank of 81 mm 902V "Tucha" smoke grenade launchers. NATO gave it the designations BMP-R and BMP M1976/1.^[1][3][9]
  • BRM-1 – With its antennae relocated to the rear of the turret.^[3]

    

  • BRM-1K (BRM stands for boevaya razvedyvatel’naya mashina – Combat reconnaissance vehicle, K stands for komandirskaya – command) – An improved command variant of the BRM-1 was developed simultaneously with it. It has all the equipment and fittings of the BRM-1 plus a few new ones. It is fitted with a mast antenna and late production models have six 81 mm 902V "Tucha" smoke grenade launchers (three on each side). It is equipped with 50 mm flares which are used for battlefield illumination. The number of firing ports was reduced from eight to three (one on each side of the vehicle and one in the rear). It is equipped with a DKRM-1 laser rangefinder, an ERRS-1 radio direction finder, a PPChR radiological-chemical detection device, a WPChR military chemical detection device, an IMP-1 mine detector, and an AB-1-P 1 kW box-shaped portable petrol-electric generator. Day/night observation devices consist of thirteen TNPO-170As, one TNPK-240A, two TNPT-1s, two TVNE-1PAs and one pair of 1PN33B night binoculars. Navigation equipment includes a TNA-3 gyroscopic apparatus, a 1G11N gyro-compass and a 1T25 survey device. The BRM-1K entered service with the Soviet Army in 1972, production started in 1973. Ammunition carried was reduced to 20 rounds for the 73 mm 2A28 Grom low pressure smoothbore gun. The vehicle weighs 13.2 tonnes. NATO gave it the designation BMP M1976/2.^[1][3][10]
    • 2S17-2 Nona-SV – Prototype Soviet 120-mm self-propelled gun based on the BRM-1K.^{[citation needed]}

Artillery reconnaissance

• PRP-3 "Val" (Ob'yekt 767, 1ZhZ) (PRP stands for podvizhnoy razvedyvatel’niy punkt – mobile reconnaissance post) – Is a BMP-1 converted into an artillery reconnaissance vehicle. It entered service with the Soviet Army in 1970 (production started in 1972 at the Kurgan Engineering Works and in 1979 at the Rubtsovsk Engineering Works). The vehicle was fitted with two R-123M or R-108 radios and optical devices which enabled it to function in the artillery/guided missile target indication, fire adjustment and/or artillery/mortar locating roles. It was armed with one PKT machine gun in a ball mount in front of the new, bigger, two-man turret which was positioned further back than in a normal BMP-1. The turret had two single-piece hatches which opened forward. Both hatches had periscopes for observation and a large optical device in front of each hatch. A shuttered housing held an optical device on the right hand side of the turret. It had a rectangular folding antenna for the 1RL126 "Small Fred" counterbattery/surveillance radar mounted in a circular hatch cover on the left of the rear of the turret which operated in the J-band and had a detection range of 20 km and a tracking range of 7 km. It also had 1V44/1G13M/1G25-1 navigational systems, a 1D6/D6M1 laser rangefinder, a 10P79 vision device, a 1PN29 night vision device and a 90 mm 2P130-1 launcher with 20 9M41 illumination missiles. The crew was increased from 3 to 5 men. One PRP was assigned to an artillery/guided missile battalion (towed or self-propelled) and to the target acquisition battery of an artillery regiment. It was also known as BMP-SON. NATO gave it the designation BMP M1975.^[1][3][4]
  • PRP-4 "Nard" (Ob'yekt 779, 1V121) The replacement for the PRP-3 "Val", it entered service with the Soviet Army in the 1980s. It was an improved PRP-3 with one 1A30M and two R-173 radios, a 1G25-1/1G13/KP-4 navigational system, a 1D11M-1 active pulsed laser range finder, a 1PN59 thermal vision device and a 1PN61 active pulsed night vision system fitted. A 1RL-133-1 "Tall Mike" retractable battlefield surveillance radar replaced the 1RL-126 "Small Fred" set. The vehicle was fitted with protected mountings on either side of the turret which house optical devices. The PRP-4 was also equipped with new electronic information processing equipment and a self-contained power supply which can be used while the vehicle is stationary. The 2P130-1 missile launcher was removed. The IFV was produced by the Rubtsovsk Engineering Works.^[3]

• • • PRP-4M "Deyteriy" (Ob'yekt 779M, 1V145) – Was a modernized version of the PRP-4 "Nard" developed in 1988. It is equipped with a 1PN71 thermal infrared vision device (which gives the crew a range of up to 3,000 m), a 1D14 periscopic laser rangefinder, a 1D13 portable laser reconnaissance device and a turret antenna mount located on the center of the turret roof behind the radar hatch.^[3]

Its left hand side optical housing flap is hinged at the top. The Rubtsovsk Engineering Works started to upgrade all vehicles of the PRP family to the level of the PRP-4MU from the 1980s. The PRP-4MU is used at regimental level. It can detect mobile and stationary targets by day or at night and under every meteorological condition.^[3]

Ammunition resupply

• BMP-1PO (This is not an official Soviet designation)– Has ammunition racks inside the rear doors and the antenna mount moved forward.^[3]

Training

• PPO-1 (PPO stands for podvizhnoy punkt obucheniya – mobile training post) – It is a BMP-1 converted into a driver training vehicle. It was developed by the CTZ design bureau. The turret has been removed and replaced by eight roof-mounted stations for the students under instruction, three down either side and two in the center. Each station is fitted with two TNPO-170 periscopes and a MK-4 sight, all of which are mounted in the forward part of the cupola, and an A-2 unit of the R-124 intercom (used via the two-way radio). The instructor has a console equipped with three cassette recorders, an AGU-10-3 amplifier, three switches, external loudspeakers and a microphone. During training each platoon is equipped with two standard BMP-1s and one PPO-1. The instructor and one of the trainees take turns to send information while rest of the trainees listen via the loudspeakers. It is also known under the designation BMP-PPO.^[1][3]

Armoured recovery

• BREM-2 (BREM stands for bronirovannaya remonto-evakuatsionnaya mashina – armored maintenance-recovery vehicle) – The turret has been removed and replaced by an armored plate.

    • Pbv 501A Command variant.^[60]

Ukraine

• BMP-1U – A limited Ukrainian upgrade of the BMP-1 developed by the State Scientific and Technical Centre of Artillery and Small Arms in Kyiv. The original turret was replaced with the new KBA-105 Shkval (‘squall’) remote weapon station (RWS) which was developed for light armoured vehicles to increase their combat effectiveness. This turret system was first displayed publicly at the IDEX 2001 arms exhibition held in Abu Dhabi, demonstrated on the wheeled BTR-3U APC. It superficially resembles the earlier Russian KBP Instrument Design Bureau TKB-799 Kliver one-man weapons station. The Shkval RWS is built mostly from domestic components and is armed with a 30 mm 2A72 automatic cannon (or the Ukrainian-produced ZTM-1 equivalent) with 360 rounds of ammunition carried onboard and a PKT 7.62 mm machine gun (or it's domestic counterpart - the KT-7.62) with 2,500 rounds of ammunition provided. Two anti-tank guided missile (ATGM) launchers were mounted on the right side of the remote turret module, capable of firing the 9M113 Konkurs missile (with a further two reload tubes carried inside) and a 30 mm AGS-17 (or Ukrainian-made KBA-117) automatic grenade launcher was installed on the left side, supplied from an ammunition box with up to 116 rounds. Additionally, a bank of six (6) defensive 81 mm smoke grenade launchers was installed on the front, lower base of the turret module. The weapons are brought on target with the OTP-20 Cyclops-1 optical and TV-based aiming complex which includes an interface for ATGM guidance. The weapons are stabilized by a new, SVWU-500 Karusel system. The entire Shkval weapons station weighs 1,300 kg with a full ammunition load. Because the new weapons station is considerably larger than the standard BMP-1 turret and its equipment takes up more internal volume, the troop compartment was reduced with the number of dismounted infantry carried dropping from 8 to 6. The first pair of roof hatches cannot be opened. The vehicle also received minor automotive upgrades, including flotation sides-skirts/mudguards and drive sprockets and tracks from the BMP-2.^[3][61] These vehicles were first revealed to the public at an armed forces parade in Kyiv celebrating Ukraine's Independence Day (August 24) in 2001 with the participation of 10 of these IFVs. In 2004, state trials of the type were concluded followed by an announcement that up to 400 BMP-1s would be upgraded to this configuration and equip 3 mechanized brigades. In reality, no more than 30 BMP-1Us were ever produced, with the Armed Forces of Ukraine only receiving 12 of these vehicles. The remaining 15 BMP-1Us were sold to Georgia in an agreement signed in 2007 and delivered prior to the 2008 Russian invasion of Georgia. Nearly all of these vehicles were lost to Russia, included 5 undamaged vehicles captured by the Russians in Gori. Three BMP-1U IFVs were sold to Chad and participated in the fighting against Islamic militants in 2013. It is unknown if any Ukrainian BMP-1Us were used in combat between 2014-2021. In April 2022, Russian state media showed what was claimed to be a trophy Ukrainian BMP-1U somewhere in Crimea with a "Z" marking. The painting of this BMP-1U indicated it may have been one of the earlier Georgian trophies.
• BMP-1M (Object 765UTB) – Evolved from the BMP-1U; unveiled in 2011. The main difference is the application of the improved KBA-105TB Shkval-A RWS in which the Konkurs ATGM launchers were replaced with the long range Ukrainian Barrier ATGM (effective range up to 5,000 m compared to 2,000 m for the Konkurs) and uses a new Tandem-2 sighting system and improved SWU-500-3C weapon stabilization system. The Tandem-2 sighting system uses two TV cameras: a narrow field-of-view (FOV) device called UTV (with a 6 km detection range for a tank-sized target and a 5 km identification range for the same) and a wide FOV ShTK camera which enables acquisition of tank-sized targets at 3 km. The system also includes a laser rangefinder. The TV-based system can operate in low-light conditions to some extent, but its performance is inferior to a proper thermal imaging system. This upgrade was offered by Zhytomyr Armour Plant for export customers, however, the only known client is Turkmenistan, which paraded the vehicles at a ceremony in 2016, implying the sale was never reported to the United Nation's arms control program. No details about the number of vehicles or transfer dates are known.

• BMP-1UM – A more comprehensive upgrade of the standard BMP-1 undertaken by the Zhytomyr Armour Plant and shown publicly in 2015. As in their previous BMP-1M, this vehicle features the Shkval-A RWS, but unlike previous attempts, considerable design efforts were made into improving the power plant and hull. The 300 hp UTD-20 engine was replaced with a 3-cylinder, two-stroke 3TD-2 diesel motor making 400 hp and sharing many parts with 5TDF and 6TD series tank engines in Ukrainian service. The troop compartment layout was improved by raising the hull roof by 15 cm, and the small, un-ergonomic egress doors at the rear of the BMP-1 were replaced by a large ramp, albeit manually operated. The external hull flanks of the IFV were lined with Kontakt-1 explosive reactive armour (ERA) bricks, which is considered questionable given the thin armour plate underlying these areas. Survivability of the troop compartment was further increased by relocating the fuel tanks separating troop seating and the hull flanks, installing larger side skirts, using an aramid fibre spall liner and providing an engineered structure under the floor of the troop compartment, designed to absorb/mitigate explosions from underneath the vehicle. The BMP-1UM was also given a SN-3003 GLONASS/GPS receiver. The commander's station TKN-3B sight was also modified to allow it to receive video feed from advanced cameras on the RWS. Finally, the vehicle's thermal signature was modified/reduced by using an exhaust gas deflector along the right side of the hull. Given the increased mass of the BMP-1UM, larger track fairings were used to ensure amphibious performance.

• BMP-1UMD – A further development of the BMP-1UM from Zhytomyr Armour Plant, unveiled in 2016 at the Arms and Security exhibition. This variant has a new RWS and engine; powered by an electronically controlled Deutz TCD2013 L64V 6-cylinder turbodiesel which produces 330 hp and is more reliable, quieter and efficient than both the UTD-20 and 3TD-2. This engine is also used in Ukraine's BTR-4 wheeled APCs. The Shkval-A was replaced by a new Stylet RWS (often called a "module" in Ukrainian sources) with a fully digital fire-control system, a brand-new sight system known as Trek-M and SWU-500-3C weapon stabilizer. The primary armament is a 30 mm ZT-2 automatic cannon (Ukrainian-made 2A42 gun), KT-7.62 coaxial MG, 30 mm AG-17 AGS and two Barrier ATGM launchers. ERA bricks were omitted in this version, replaced by extended mesh covers along the upper hull sides. Curiously, the BMP-1UMD project made no changes to the BMP-1's troop compartment, with the original access doors and troop layout. The Ukrainian Ministry of Defence did formally trial vehicles equipped with Shkval and Stylet RWS modules, however their results are not public and no orders were made, hinting at their less than satisfactory performance.
• BMP-1 – Converted into an ARV.^[62]

• BMP-1TS – Upgrade variant developed by Ukrainian private enterprise; Techimpex have been working on a RWS for the BMP-1 named Spys since 2018. Its armament consists of the usual assortment of on-board weapons: 30 mm ZTM-1 automatic cannon (with 300 rounds of ammunition), KT-7.62 MG (with 350 ready rounds of ammunition and a total of 2,100 rounds carried), a 30 mm KBA-117 AGS (with 116 rounds onboard, 29 ready to use) and Barrier ATGM (4 missiles carried of which 2 are ready to launch). The Spys module received the Syntez fire-control system consisting of Kazhan-3K15 sighting complex with both thermal and optical TV cameras as well as a laser rangefinder. Combat effectiveness is enhanced with an electro-mechanical 2-axis weapon stabilization system. The advanced software used in the Spys module allow for automatic target tracking. Its small overall dimensions mean that it is interchangeable with the original BMP-1 turret with no modifications required. The upgrade package does not include any changes to the chassis or automotive qualities of the BMP-1, and the only other addition is a Motorola DM4601 radio. Further mine and ballistic protection are only available as options. 10 vehicles were ordered by the Ukrainian defence ministry and unveiled at the 2021 Independence Day parade. At least 1 vehicle belonging to the 53rd Mechanized Brigade was lost in the city of Volnovakha in March during the 2022 Russian invasion of Ukraine.

Vietnam

• XCB-01 (XCB likely stands for Xe Chiến đấu Bộ binh – Infantry fighting vehicle (IFV)) – 2022 Vietnamese local resemblance of the BMP-1. It is largely similar to the original Soviet variant except having a bigger chassis size for a considerably wider internal space, a diagonal welded turret with the addition of smoke launchers and a 12.7mm machine gun (Kord or NSV) on top of the platform. Yet to be formally revealed but at least one prototype has been reportedly leaked on the social media.^[63][64]
