The M-84 is a Yugoslav main battle tank based on the Soviet T-72. It is still in service with Bosnia and Herzegovina, Croatia, Serbia, Slovenia and Kuwait.
The M-84 is based on the Soviet T-72M, the export variant of T-72A, with many improvements, including a domestic fire-control system that the T-72M lacked, improved composite armor, and a 1,000-hp engine. [1] The M-84 entered service with the Yugoslav People's Army in 1984, and the improved M-84A version entered service a few years later. Other variants were introduced later, most being modernization packages.
About 240 Yugoslav factories directly participated in the production of the M-84, and about 1,000 others participated indirectly. [2] The manufacturer was chosen by Josip Broz Tito to be the Đuro Đaković in Croatia, over other proposed manufacturers in Serbia: Goša FOM Smederevska Palanka and Mašinska Industrija Niš, at that time the biggest producers of locomotives and wagons in Yugoslavia. [3] The biggest manufacturers directly involved in production of the M84 main battle tank in SFR Yugoslavia and Federal Republic of Yugoslavia among former republics were:
The M-84ASA, a Serbian version of the M-84, was unveiled in 2004. It has a new fire control system, Kontakt-5 ERA armor, AT-11 Sniper anti-tank missiles, Agava-2 thermal sight, and the Shtora defensive suite. It is very similar to the Russian T-90S in appearance and in capability. The latest prototype version from Serbia, M-84AS1, unveiled in 2017, has a new fire control system with domestic laser and radar warning system, RCWS 12.7mm and soft active protection suite with a new version of domestic explosive reactive armor (ERA). A later prototype of the same tank unveiled in 2020 has better-shaped ERA M19 reactive armour, some new situational awareness equipment, and new ammunition. [19]
About 150 M-84 tanks were exported to Kuwait. The disintegration of Yugoslavia in the 1990s prevented further exports of the M-84. [1] Sales of the M84 including negotiations of contracts with foreign partners were done through Yugoimport SDPR, at that time acting as a Yugoslav state agency. Production and delivery was performed by Đuro Đaković.
The M-84A is armed with a 125 mm smoothbore cannon derived from the Soviet 2A46. The fume extractor positioned in the middle of the barrel is shielded with a thermal coating that minimizes deformation of the barrel from high temperatures and ensures it is cooled at the same rate during rapid firing. The M-84 uses an automatic loader, which enables it to sustain a firing rate of 8 rounds per minute.
The cannon's 40 rounds of ammunition are stowed in the hull of the tank beneath the turret. This concept was inherited from the original Soviet design for the T-72, and is both a strength and weakness of the tank. The lower hull beneath the turret is one of the least likely place to be hit and penetrated by antitank rounds or mines, but in the event of penetration and secondary detonation of the ammunition the crew and tank are unlikely to survive the resulting catastrophic explosion.
Along with its primary armament, the M-84 is also armed with one 7.62mm coaxial machine gun, and one 12.7mm anti-aircraft gun mounted on the commander's turret.
All versions of the M-84 have a crew of three. The commander sits on the right side of the turret, the gunner on the left, and the driver sits centrally at the front of the vehicle. Like most Soviet-derived vehicles, the M-84 series of tanks have an autoloader rather than a manual loader.
The basic tank has a cast steel turret with maximal thickness of 410mm; later, in the M-84A version, a segment made out of a non-metal, most likely rubber and boron carbide (see Chobham armour), was sandwiched between layers of steel. The glacis uses laminate armor, glass in plastic resin between two steel plates; in the A version a 16mm steel plate was welded on the glacis. Total armor protection ranges between 550mm-650mm for the glacis and 560mm-700mm for the turret. During the wars in Yugoslavia the M-84's frontal armor proved very effective against any type of AT threat.[ citation needed ] Side or rear hits often result in a catastrophic ammo explosion.
Twelve smoke grenades are positioned in front of the turret in banks of five and seven grenades. Night vision and gunner's sights are positioned on the top-right side of the turret. The M-84 has a searchlight used in short-range combat situations.
The M-84 tank has nuclear, biological and chemical (NBC) protection capabilities.
The base M-84 engine is a 12-cylinder water-cooled V46-6 diesel engine, rated at 574 kW (780 hp). The improved M-84A has a more powerful, V46-TK 735 kW (1,000 hp) engine. With maximum fuel load of 1,200 litres the tank's range is 450 km, extendable to 650 km, with external fuel tanks.
The Croatian-made variants have enhanced power plants. The M-84A4 Sniper model has a German-built 820 kW (1,100 hp) engine, while the M-84D has an 895 kW (1,200 hp) engine, the most powerful of all M-84 variants. The M-84D also has greater fuel capacity (1,450 litres).
The tank can ford 1.2 meters of water, increasing to 5 meters with a snorkel.
Before the Persian Gulf War, Kuwait ordered 170 M-84ABs, 15 M-84ABI ARVs and 15 M-84ABK command tanks, from Yugoslavia. Four M-84A tanks were delivered; however, the Iraqi Army soon captured them after the occupation. Further deliveries were stopped for the duration of the war. The Kuwaiti 35th Al-Shaheed Armored Brigade was equipped with 70 M-84s. [1] During the retaking of the country, the 35th Brigade did not directly take part in battles with Iraqi tanks because of the M-84's similarity to Iraqi T-72 or Asad Babils. The M-84 was however very effective against T-62s and T-55s but some unconfirmed reports claim that a few of them were damaged, but recovered and repaired.
During the Ten-Day War, the Yugoslav People's Army (JNA) attempted to regain control over border crossings, airports and other strategic positions in Slovenia. The Slovenian Territorial Defence had no armoured units of its own and JNA M-84s were commonly used to break through barricades. Slovenia inherited all the M-84s within its territory, once the ceasefire and Slovenia's independence was accepted.[ citation needed ]
The M-84 saw action in the Battle of Vukovar, where the JNA employed tanks against Croatian National Guardsmen (ZNG). Although the JNA ultimately prevailed, it's estimated they've lost around 100 tanks, including 20 M-84s to minefields and ambushes by ZNG anti-tank teams. Four of these M-84 tanks were knocked out during an ambush on Trpinjska Road, though entrenched JNA M-84s were successful in defeating a Croatian counteroffensive, knocking out three T-55 tanks. [1]
During the Bosnian War, M-84s were used by Croatian forces in the Krajina region, and in the Siege of Sarajevo by both the Army of Republika Srpska (VRS) and (in smaller numbers) the Army of the Republic of Bosnia and Herzegovina. [1]
In the mountainous terrain of the Bosnian theater, the limited main gun elevation/depression proved to be a problem, while the use of Pakistani-supplied HJ-8 anti-tank guided missiles by Bosnian forces proved to be a threat. While the frontal armor of the M-84 was reportedly never penetrated during the conflict, around 40 M-84s were lost by all sides (though some were repairable) at the end of the conflict, mostly from hits at the thinner lower-side armor or anti-tank mines penetrating the belly armor, causing the ammuntion stored in the crew compartment to detonate, often resulting in turrets popping off. [1]
The M-84 was used by Yugoslav ground forces in the Battle of Oraovica during the Insurgency in the Preševo Valley. [1]

The Army of Republika Srpska, commonly referred to in English as the Bosnian Serb Army, was the military of Republika Srpska, the self-proclaimed Serb secessionist republic, a territory within the newly independent Bosnia and Herzegovina, which it defied and fought against. Active during the Bosnian War from 1992 to 1995, it continued to exist as the armed forces of RS, one of two entities making up Bosnia and Herzegovina, until 2006 when it was integrated into the Armed Forces of Bosnia and Herzegovina. Forces of the VRS engaged in several campaigns, including Operation Corridor 92, Operation Vrbas '92, Operation Bura, and Operation Spider; they were also involved in the siege of Sarajevo, as well as the Srebrenica massacre.
The Republic F-84 Thunderjet is an American turbojet fighter-bomber aircraft. Originating as a 1944 United States Army Air Forces (USAAF) proposal for a "day fighter", the F-84 first flew in 1946. Although it entered service in 1947, the Thunderjet was plagued by so many structural and engine problems that a 1948 U.S. Air Force review declared it unable to execute any aspect of its intended mission and considered canceling the program. The aircraft was not considered fully operational until the 1949 F-84D model and the design matured only with the definitive F-84G introduced in 1951. In 1954, the straight-wing Thunderjet was joined by the swept-wing F-84F Thunderstreak fighter and RF-84F Thunderflash photo reconnaissance aircraft.
The Yugoslav People's Army, also called the Yugoslav National Army, was the military of the Socialist Federal Republic of Yugoslavia and its antecedents from 1945 to 1992.
The M36 tank destroyer, formally 90 mm Gun Motor Carriage, M36, was an American tank destroyer used during World War II. The M36 combined the hull of the M10 tank destroyer, which used the M4 Sherman's reliable chassis and drivetrain combined with sloped armor, and a new turret mounting the 90 mm gun M3. Conceived in 1943, the M36 first served in combat in Europe in October 1944, where it partially replaced the M10 tank destroyer. It also saw use in the Korean War, where it was able to defeat any of the Soviet tanks used in that conflict. Some were supplied to South Korea as part of the Military Assistance Program and served for years, as did re-engined examples found in Yugoslavia, which operated into the 1990s. Two remained in service with the Republic of China Army at least until 2001.
The M-95 Degman is a prototype Croatian main battle tank, developed in 2003 by the Đuro Đaković company and is largely based on the older M-91 Vihor tank that was based in the M-84 tank. The Đuro Đaković factory is best known for its principal role in the production of the M-84 in the Yugoslav era.
NORA M-84 is a Yugoslav and Serbian 152 mm and 155 mm gun-howitzer developed by the Military Technical Institute (MTI) for the Yugoslav People's Army, Serbian Army, and export. Gun howitzer NORA has three basic versions, and is usually towed by a FAP 2026 BS/AV truck.

The M-84AS prototype main battle tank is a modernized version of the M-84 produced by Yugoimport SDPR in Serbia. M-84AS is sometimes referred to as M-84AB1 and M-2001 and is based mostly on imported components.
The Yugoslav Ground Forces was the ground forces branch of the Yugoslav People's Army (JNA) from 1 March 1945 until 20 May 1992 when the last remaining remnants were merged into the Ground Forces of the new Federal Republic of Yugoslavia, under the threat of sanctions.
The T-72 is a Soviet-designed main battle tank that entered production in 1973. It replaced the T-54/55 series as the workhorse of Soviet tank forces. In front-line Russian service, T-72s are being upgraded or augmented by the T-90, itself a modernized version of the T-72B. The T-72 has been exported and produced in many countries.
The AMX-30 AuF1 is a French self-propelled gun vehicle currently in use by the armies of France and Saudi Arabia. It replaced the former Mk F3 155mm in French Army service. The AuF1 primary advantage is that it incorporates full armor and nuclear-biological-chemical (NBC) protection for its crew of four, while the former Mk F3 155mm offered no protection and could carry only two of its four crew members. The AuF1 saw combat with the Iraqi Army in the Iran–Iraq War.
