T-74 Borov is a main battle tank that served as the primary tank of the Stasnovan Armed Forces from 1974 to the early 2000s. It has had various upgrades over the years, making it a formidable tank even in modern battlefields. It has since been exported to various countries. Its latest uprgades still serve in the Stasnovan Amred Forces in large numbers, and many tanks left unupgraded and are currently in storage will either be up upgraded and returned to service, sold to other states or scrapped.
The development of the T-74 began as a result of the introduction of the T-67 Veter (Object 267) in the Stasnovan Revolutionary Army for active service. A competition was started by Army Command for the Stasnovan design companies to build a main battle tank that would supplement and eventually replace the T-67. Orelvagonzavod's prototype, the Object 274, was completed before even the rival company, the Tormavkovo Mozhaev Military Design Bureau (that designed the T-67), even put it in production. The Revolutionary Army's leadership was satisfied with the new tank, and decided to adopt it, with the designation T-74.
The T-74 formed the backbone of the Stasnovan tank units from the 70s to the early 00s, when the T-94 Kulak was introduced in 2003. It was exported to numerous countries, such as Cydonia, Republika Srpksa, Sarasir, Sego, and has been copied and produced elsewhere, both with and without licenses.
Licensed versions of the T-72 were made in Cydonia by the Yika Urenograd Tractor Factory, and were essentially copies of their Stasnovan equivalents, with in some cases, the same designation. While Vastava Pact nations received non-downgraded versions for the most part, as per Stasnovan policy, non-VP states received downgraded "monkey models", like the T-74S and its variants, and in some cases (such as Sarasir), where allowed to produce them.
Republika Srpska has produced a licenced copy of the T-74S, the M-87, and the neighbouring Republic of Oskorev also uses them in extremely limited quality. Sarasir has built an unlisenced devirative of the export version, the Zuljanah. The tank is estimated to be on par with the T-74S1, and serves only with the elite Sarasir Republican Guard. A number of T-74 variants has also been built in Elesar, before the fall of the Socialist government and exit from the Vastava Pact. The Ordian government was granted production rights for the T-74S1 in 1980 (after 800 T-74S units had already been delivered since 1976), and the production rights for the more advanced T-74S1 and T-74S2 variants were granted later on. Ordia has produced roughly 1,700 tanks.
The T-74 along with some older tanks in Stasnovan service saw action during the First Rekovian War. In the Siege of Grazdnovo, Stasnovan T-74 firing positions shelled the high rise buildings of the city that housed separatists, and effectively used Kobra tank-launched missile to strike targets beyond the range of their main guns. The Stasnovan Revolutionary Army used the T-74 extensively against Rekovian Lord's Army (RLA) armored formations, particularly in the Battle of Kvartira. During the battle, the 2nd Guards Tank Regiment, part of the 2nd Guards Moskvingrad Motor Rifle Division faced off against the "Kvartira" Brigade (officialy known as the 74th Seperate Tank Regiment, a SRA unit that defected to the RLA), commanded by Colonel Georgy Taziev, in an open field outside the town. Both sides were equipped with T-74 variants, though the 2nd possesed T-74M2 and T-74M1 variants, while the Taziev's Brigade- being a reservist unit -was equipped with older T-74A and T-74B variants. The battle was described as the largest tank battle of the war by many analysts and historians. The initial Stasnovan attack resulted in 32 of Taziev's tanks getting destroyed, with only 4 Stasnovan losses (3 T-74M1s and 1 T-74M2), something also attributed to the superior trainning of Stasnovan crewmen and the Stasnovan air superiority. In the urban battle that followed, 13 more of Taziev's T-74B/T-74As were also destroyed/knocked out, with only 2 Stasnovan losses in exchange.
In the urban fights during the Siege of Grazdnovo, the RLA separatists made extensive use of infantry anti-tank weapons, knocking out/destroying 8 T-74M1s and 2 T-74M2s. In all cases, the tanks were destroyed when hit in the side or on the top, the frontal armor was never penetrated, with both of the PRB-74M2 being destroyed by AT mines. According to Stasnovan sources, the Active Protection Systems on the T-74M1s wokred perfectly.
The T-74 was used by both sides of the Stasno-Dagelian War. The Stasnovan Revolutionary Army's 25th and 31st Guards Motor Rifle Divisions mostly made use of the more modern T-94 Kulak main battle tank, however, the 31st Guards Motor Rifle Division supporting 56th Tank Regiment employed T-74M3s in its 167th and 168th Tank Battalions. Both T-94 and T-74 tanks, as well as other vehicles in Stasnovan service were fitted Combat Identification Panels (CIP), due to the similarity the bared with Dagelian AFVs. Generally, Stasnovan T-74M3s outclassed the Dagelian T-74Sim-1 and other variants.
The Dagelian variants were mostly the T-74Sim-1, T-74Bs and some T-74As, though the last didn't see much combat. The T-74Sim-1 was upgraded by Template:COUNTRY for the Dagelian Land Forces, and featured increased ERA implementation, new command and control and GPS navigation system, as well as fire control system with thermal imager and laser rangefinders. Despite all these upgrades, the T-74Sim-1 proved inferior to the Stasnovan T-94A/AM and T-74M3. However, Dagelian T-74Sim-1s proved effective against older T-74Bs and T-62Ms of the South Ossetian militia forces, with several kills documented.
One documented tank duel was between a Stasnovan T-74M3 commanded Lieutenant Ivan A. Kartsev and a Dagelian T-74Sim-1 outside Chekhavali. The engagement range was more than 2,800 metres, giving the advantage to the more advanced optics of the T-74M3. The Dagelian tank fired three APFSDS shells, with two missing and the third hitting T-74M3 in the front of the turret. The round was deflected by the heavy "Zashchita" ERA. Karstev's tank, that was until the second incoming shot unware of the T-74Sim-1 as it was engaging other targets, returned fire with two APFSDS rounds, with one hitting the left track of the Dagelian tank, imobilising it, and the second hitting directly on the right side of the main gun, detonating the ammunition and causing a catastrophic kill.

The T-74 is equipped with the 125 mm (4.9 in) 4A76 series main gun, a significantly larger calibre than the standard 105 mm (4.1 in) gun found in contemporary MBTs, and still slightly larger than the 120 mm found in many other modern MBTs. As is typical of Stasnovan tanks, the gun is capable of firing anti-tank guided missiles, as well as standard main gun ammunition, including HEAT and APFSDS rounds. The T-74's main gun is fitted with an integral pressure reserve drum, which assists in rapid smoke evacuation from the bore after firing.
The T-74 also features a carousel-type automatic loader that can load the main gun is about 6-8 seconds. The autoloader system also includes an automated casing removal mechanism that ejects the propellant case through an opening port in the back of the turret during the following reload cycle. The autoloader disconnects gun from the vertical stabilizer and cranks it up three degrees above the horizontal in order to depress the breech end of the gun and line it up with the loading tray and rammer. While loading, the gunner can still aim because he has a vertically independent sight. With a laser rangefinder and a ballistic computer, final aiming takes at least another two to four seconds, but it is pipelined into the last steps of auto-loading and proceeds concurrently.
In addition to the 22 auto-loaded rounds, the T-74 carries 17 rounds conventionally in the hull, which can be loaded into the emptied autoloader trays or directly into the gun.
The basic PRB-74 is well relatively powered, with a 850 hp. The 0.59 m wide tracks run on large-diameter road wheels, which allows for easy identification of the T-74 and descendants. Different versions of the T-74 have been by more powerful engines. The E-850 can attain a top speed of 70 km/h on the road and up to 50 km/h on rough terrain. The tank is also fitted with an air conditioning system for work in high temperature zones.
Armour protection of the T-74 was strengthened with each succeeding generation. The T-74A featured a new turret with thick but nearly vertical frontal armour. The cast steel turret included a cavity filled with sand.
Several T-74 models featured explosive reactive armour (ERA), which increased protection primarily against HEAT type weapons. Late-model T-74 tanks featured heavy ERA to help defeat modern HEAT and AP.
The T-74B, featured improved turret and hull armour. The T-74B used a new "reflecting-plate armor" , in which the frontal cavity of the cast turret was filled with a laminate of alternating steel and non-metallic (rubber) layers. The glacis was also fitted with 25 mm of appliqué armour. The T-74 also featured an anti-radiation layer on the hull roof.
The T-74 also has a comprehensive nuclear, biological, and chemical (NBC) protection system.
The Cydonian Armed Forces were to initially receive a batch of T-74S export variants in 1975, however, a change in Stasnovan military hardware export policy allowed the Cydonians, as well as every Vastava Pact member to purchase the standard, non-downgraded versions of said hardware. Thusly, the Cydonian Army received 200 baseline T-74s, and the Cydonian government also signed a deal with their Stasnovan counterparts for domestic production of the tank, plus the production of their own variants. Cydonia is the second largest operator of T-74s after Stasnov.
The Vilats Union Armed Forces originally received 100 T-74s in 1977, followed by another 50 T-74As in 1980. In the next five years, the Vilatic Army received 100 additional T-74As, and beginning in 1986, deliveries of T-74Bs also started. In 1991, the Vilatic military also ordered an unspecified number of T-74M1s to also be delived in a single batch, with the deliveries completed by the mid-90s.
