T-72M4 CZ


The main impetus for the modernization of tanks series T-72 in Czechoslovakia, respectively. The Czech Republic and the Slovak Republic became the experience of the Wars in the Persian Gulf from 1991, when the last generation of Western tanks clearly declassified in a number of parameters the most modern tanks introduced in the Iraqi army, which were just T-72 (it is not without interest that at least 90 Iraqi specimens were produced in 1980s in Czechoslovakia).


The main goal of the modernization effort, the origins of which in the case of Czech modernization date back to about 1994, were the following:
- increasing the probability of hitting stationary and moving targets during the day, at night, with reduced visibility and while moving
- Increasing the firepower of the tank with more efficient ammunition
- Increasing the tank's ability to survive in combat
- increase in mobility
- improvement of tank operating characteristics (greater reliability, easier maintenance and operation)


In 1995, the Ministry of Defense selected the company VOP 025 Nový Jičín as the main implementer of the modernization. In February of the same year, tenders were announced for suppliers of the main modernized tank groups. At the beginning of 1996, construction work began and by the end of 1996, the first modernized tank was built T-72M3 CZ. The main difference between this version and the final version is the largely identical movement system consisting of the original transmissions and a more powerful version of the original engine marked V-46TC with two turbochargers. The second prototype, this time representing the final variant of the T-72M4 CZ, was completed in April 1997. While the version M3 was mobility and maneuverability almost the same as the unmoderated tank, then a significant improvement was achieved in the M4 version.


The biggest difficulties that arose during the testing phase were caused by the integration of the Italian fire control system TURMS-T. Problems with this facility have persisted since the summer of 1997 and were successfully resolved only three years later thanks to the assistance of the Slovak company EVPÚ from Dubnice nad Váhem. By the end of 2000, all company, military and control tests were completed, so the modernized tanks had an open path to the ACR armament. The last unresolved issue was the number of tanks undergoing modernization. The original requirement for 350 tanks was reduced to 140 copies in April 2001 by a government resolution, but as it turned out, the economic reality of the Czech Republic was still a high number. Based on an economic analysis from August 2001, a contract was signed on November 30 of the same year for the supply of a 30-piece series, which was designed to arm one tank battalion. In 2003, the modification of the first tank from the verification series of 5 pieces was started. In the same year, tests of this verification series were performed. At the end of 2003, there was 73. mixed mechanized battalion (at the beginning of 2005 the unit was transformed into 73rd Tank Battalion) delivered the first nine pieces . Production continued the following year with the production of another eleven copies. Deliveries of 27 T-72M4 CZ tanks were completed in 2005. This year, eight pieces were handed over (including one command), the remaining two command T-72M4 CZ-W were then delivered to the army on February 28, 2006. Of all the tanks produced, there were three in the command version T-72M4 CZ-W. In 2007, the delivery of three rescue machines followed VT-72M4 CZ. As part of the modernization, 5 sets of modernization components for spare parts for the T-72M4 CZ were also delivered.In 2007, deliveries of elements of the classroom-training base took place: 3 pieces of SO-72M4 crew simulators and 27 pieces of teaching lessons for 2 methodological workplaces - CBT classrooms.


Unlike the Polish modernization PT-91M, the Czech T-72M4 did not see any export success. The price of 27 T-72M4 CZ tanks in the basic version was 4.443 billion CZK. Together with them were bought 3 trailer bulldozers NBZ-90, 3 mine harvesters KMT-72M4, 3 explosive deminers VO-72M4 and other equipment, which increased the price to CZK 4.953 billion.


The basis of the modernization of the T-72M4 CZ tank became cars T-72M. During the conversion to the M4 standard, the tank was first disassembled, while the tower and the hull underwent major modifications (replacement of the rear face of the hull, replacement of the bottom of the hull under the driver, modification of the engine compartment for mounting a powerpack, etc.). Over 90% of parts, groups and subgroups are either new or modified in the design of the modernized tank. The installation of dynamic protection and other modernization elements increased the weight of the T-72M4 CZ tank (compared to non-modernized versions) by about 6,000 kg. For this reason, the chassis was strengthened and stronger torsion bars were used. In addition, flexible stops have been added to all wheels.




Modernization elements


Armament
The original cannon 2A46 (D-81) is equipped with a new thermal jacket, ejector and mouth rectification system. To increase the firepower against armored targets in the Pardubice Synthesis was developed and introduced into the military armament sub-caliber missile 125/EPpSv-97, which is able to pierce over 500 mm of homogeneous armor at a distance of more than 2000 m. This missile can be used in all T-series tanks. -72.


The cannon has a minimum effective range of shooting during the day:
- for sub-caliber arrow projectile: 2 200 m
- for a fragmentation projectile: 2 000 m
- for cumulative projectile: 1 900 m

Effective range of shooting at night:
- for all types of ammunition: 1 800 m



Self-protection systems
The original armor of the tank was reinforced in the area of the hull and tower with a suspended dynamic protection DYNA consisting of 124 segments, which together contain 95 kg of plastic explosives. DYNA also has declared resistance to tandem cumulative bullets.


The outer surface of the tank is coated with a microwave absorber, which reduces the radar reflection of the vehicle. During stops, a thermal mat can be used, which covers the engine compartment, thus reducing the level of thermal radiation of the vehicle.


The Polish SSC-1 laser radiation detection and indication system OBRA provides detection and indication of tank irradiation with a laser rangefinder or laser irradiator. At the same time, it allows automatic firing of smoke grenades in the direction of irradiation. The tank has a total of twelve VZ 902 throwers for smoke grenades DGO-1.


The fire protection system is from Kidde Deugra and consists of two independent systems. The first is designed to extinguish a fire in the engine-transmission area, the second is to extinguish a fire in the combat area.



Instrumentation
The fire control system (SRP) with the ability to search for and destroy targets at night and in difficult weather conditions is of the TURMS-T type from the Italian company Officine Galileo. The system works with a ballistic computer that receives and processes information from sensors in the vehicle. The monitored data include, for example, vehicle speed, tank lateral and longitudinal tilt, wind direction and speed, or powder charge temperature. The computer further analyzes the data about the target, which are mainly its distance, direction and speed of movement. The time of complete start of the SRP during the day is 30-120 seconds, depending on the air temperature, and at night up to 480 seconds. The time to the first shot at a fixed target is 5 seconds, at a moving 10 seconds.


T-72M4 CZ is equipped with a diagnostic unit DITA 72/97B, which collects and analyzes data from sensors distributed throughout the tank. In the event of a fault, it then informs the crew.The diagnostic unit is also able to intervene in the performance parameters of the tank, in the event of an imminent accident of some subgroups (engine, transmission), the vehicle can stop completely.


The tank is equipped with the BVIS system (combat vehicle information system), which includes GPS navigation with a map base and is able to display information about the location of other vehicles of the unit. The position data of the enemy vehicles can also be entered into the BVIS.


Observation and optical instruments are also new. The shooter has an observation device stabilized in two planes, in which a laser rangefinder and thermal imaging camera are integrated. The tank commander uses a panoramic binary stabilized observation device with a thermal imaging camera.


The connecting means of the T-72M4 CZ tank consist of a radio station RF-1350, its accessories and the BCC 600A tank call device.



Mobility
The modernized tank is equipped with an Israeli powerpack, which consists of a British Perkins CV-12-1000 TCA Condor engine and an American XTG 411-6-N automatic transmission. The engine has liquid cooling, air is supplied to it via two turbochargers with a compressed air intercooler. The distribution is of the OHV type. The installation of a powerpack in the vehicle forced the extension and increase of the original body. The internal fuel supply is 1,145 liters, and a fuel barrel with a volume of 195 liters can be attached to the rear of the tank. Consumption on the road is around 350 liters per 100 km, in the field up to 800 l/100 km.


To monitor the rear hemisphere, the tank is equipped with a camera, the image of which is projected to the driver on a color display and allows him to reverse independently and observe the situation behind the vehicle.

Tank Battalion, exercise Saber Junction II / Combined Resolve 2013, Hohenfels training area, Germany, 20 November 2012. The Saber Junction II multinational exercise took place from 9 to 22 November 2013 at the Combined Multinational Training Center in Hohenfels, Germany, with the participation of 587 Czech soldiers and 130 pieces of military equipment. The exercise focused on conventional warfare and the soldiers practiced all types of combat activities. In terms of the number of soldiers and equipment deployed, it was one of the largest and most important foreign exercises for the Czech Army. The Czech task force, designated TF 72 (the core of which was made up of members of the 72nd Mechanised Battalion from Přáslavice), was the main combat force of the multinational brigade controlled by the commander and staff of the 173rd Airborne Brigade Combat Team.

It is remarkable that the Ministry of Defence is unable to arrange the transport of military equipment to its own events with its own transport capabilities. This tank was thus transported from its parent garrison and then back to the Tank Day using the transport equipment of a civilian company for the amount of CZK 74,052 including VAT.

Modernization of T-72M4 CZ tanks for the Czech Army

On Monday 14. September 2020, the Deputy Minister of Defence for the Management of the Armaments and Acquisitions Section of the Ministry of Defence Lubor Koudelka and representatives of the contractor VOP CZ, company director Radovan Putna and commercial director Martin Krupa, concluded a contract for the technical evaluation of all tanks of the T-72M4 CZ type series with the performance until the end of 2025.

The subject of the public contract is the technical evaluation of 27 units of battle tanks T-72M4 CZ, 3 units of command tanks T-72M4 CZ-W and 3 units of recovery tanks VT-72M4 CZ. The essence of the technical evaluation will be the replacement of obsolete components of the fire control system within the rearmament of the 7th Mechanised Brigade according to the approved strategic programme of the Government of the Czech Republic. Furthermore, compatibility at the level of communication means (voice and data transmissions) will be ensured thanks to the installation of American radios from HARRIS.

The subcontractors VOP CZ will be the Czech companies Mesit and Delinfo, which will ensure the modification of the internal communication equipment and the data link, the Italian company Leonardo, which will modernize the fire control system, the German company Kidde-Deugra, which will ensure the evaluation of the firefighting equipment, and the Slovak company EVPÚ, which will reprogram the fire control computer.

This technical evaluation of the tanks T-72M4 CZ will extend their service life until at least 2030. According to the contract, the final value of the contract is a total of CZK 1.098 billion, including VAT. The government took note of the implementation of the contract at this value in June 2019, with the expected performance in 2019-2023.

However, more than a year of negotiations followed on the exact scope of the modernisation, the value of which could almost double to CZK 1.8 billion, excluding VAT, due to additional requirements. A spokesman for the Ministry of Defence commented:"At the beginning of the project, only the modernisation of the gunner's and commander's targeting system with the replacement of communication systems was planned. Then the project was expanded to include the propulsion units and the firefighting system. And it was the modernization of the essentially unique engines on these tanks that would have increased the contract price compared to the original assumptions."

But this requirement was ultimately not implemented, which the spokesman commented by saying. The propulsion units are regularly serviced and will therefore continue to be provided with standard after warranty service and will not be subject to any upgrades."

As a result of this development in the upgrade project, the timing of the entire contract has therefore been delayed. Its completion is expected to be delayed by two years compared to the original expectation.

Diskuse

Gentlemen,
according to an undated figure posted on the Global Security website, the cost was projected at $4 million per T-72M4 tank.


A figure of $3 million per unit was posted on the Main Battle Tanks i-site in 2002.


The figures published in the following AVIS brochures, available in hard copy and electronic form, are considered authoritative


The AVIS Yearbook 2004
Page 5 states:
"The total cost of the delivery represents an amount of about 6.8 billion CZK (the price of one T-72M4CZ unit is on average about 140 million CZK). The tank deliveries are being carried out in accordance with the concluded contract. By the end of 2004, a total of 20 modernised T-72M4CZ tanks out of a total of 30 units had been delivered (by 2006, the last 3 units with command equipment). The deliveries include a comprehensive solution for the supply of the training base and logistic support."


Upgraded T-72 to armament
From the text of page 3 it can be deduced:
- For the first ten machines the price per unit is 150 million CZK,
- for the remaining twenty machines the price per unit is 120 million CZK.
- CZK 3.9 billion will be spent on the delivery of 30 machines.

For the T-72M4CZ, a sub-calibre tungsten-core dart missile was developed, very effective against armoured vehicles with reactive armour. Unfortunately (for financial reasons), the modernisation omitted the reloading machine, ammunition storage, stabilisation action members and main armament.

I saw that instead of the short "tomato" handles there are "handlebars" on the M4CZ - what is the difference in comfort of operation, do you have experience? Otherwise, I kind of envy those who have the opportunity to at least occasionally drive these machines (it's actually been quite a while since I last closed the hatch of my BVP, BPzV or T-bird "driver's license" over me), but I'm busy enough to join them...

I have no experience with CeZeta. Now we have finished our driving licenses for T-72 and originally we were supposed to be retrained for CeZetas. This was when one company was supposed to be pro (10 tanks), the other company reservists (10 tanks), and the other 10 tanks in eNZets. But now the situation has changed. There will be two companies of pro's (2x10 tanks) and 10 tanks in eNZets (but that's when there will be all 30 units). Our company will probably stay on T-72 M2 or M1. We should get 10 units and one recovery vehicle. I think it's better that way, but of course I'd like to ride the CeZeta as well. I don't think that's gonna happen. The situation in the army is always changing.

sorry to bring up such an old thread... but there are already 2 profi tank companies in Praski, and a third company is being built by the end of 05... So far I'm filled with AZD, who use M1... however, 3rd tr is already taking over M4s.
Driving with CeZeta is one step better than driving with other armored vehicles, but the driver has to learn how to handle the automatic, because it has a bit of a lag, so he has to add throttle already when he goes into the ditch, to get out of it quickly and dynamically, etc...
If there are any questions on CZta, just ask Smile
by the way, CZta does NOT have a 2A46M cocoon as it says everywhere... it has a 2A46

Pretty pics Smile. Can I ask how the new fire control system is working in the field?



mno, ad pics... thank you Smile
And with the question... try to be more specific. this way, I just have to say that the manufacturer gives a 95% probability of hitting the first shot at 2000m. In driving, up to 90%. It doesn't matter if the target is static or moving.
Otherwise, of course, the system has its limits. Especially the stab is not designed for firing at full speed in the terrain, it is not a problem to load clay into the stock... which then has a negative effect when firing...
So what exactly are you asking? Smile


Btw, I don't know if it's been mentioned here before, but the Model 85 barrel is used for target practice. The 14,5mm round is the same as the classic.

what's the big deal, svezenicko in it is great Smile especially eliminates constant checking of temperatures and pressures in the engine... everything is monitored by diagnostics... and any errors are reported by the driver and the commander on the DDU and CDU even if the commander's CDU is changed to BVIS...

So I'm a little off on the shortcuts. Could you explain it a little bit for the rest of us? Those of us less experienced, who only had a bunch of alarms to watch and the commander and gunner guessing where their turret was by the wheel by the turret motor, have no idea what we're talking about. Also photos would be handy if you can. Otherwise, I'm pretty jealous.

The probability of a hit is of course classified and therefore cannot be disclosed by the manufacturer. 2000 m is the so-called effective firing range for a three-shot bursting projectile, the so-called OF (oskulachno-fugasnyj). For a subcaliber BM missile it is 2200 m and for a cumulative BK missile it is 1900 m. Different hit probabilities are defined for these types of munitions and distances for different types of shooting tasks. The percentages quoted are not correct, but as an advertisement it's good.


Shot ammo is sometimes used in training, but only on a limited basis, although I don't think it makes logical sense since the military disposes of excess ammo.

T-72M4


VOP 25 Štenberk


The tank is designed to destroy tanks and other armoured targets, or. It is armed with a 125 mm smoothbore gun, stabilized in two guidance planes with a rate of fire of up to 8 rounds/min and an automatic reloading device. It is also armed with a 7.62 mm PKT machine gun coupled to the cannon and a 12.7 mm NSV anti-aircraft machine gun. It is also possible to use the 7.62 mm vz. 95/98 machine gun with original ammunition and NATO ammunition. The tank is equipped with a device protecting the three-man crew and the vehicle's internal equipment against pressure wave, radiation and chemical agents. The tank has a device for crossing watercourses by driving underwater, a fogging device to create smoke screens for camouflage and a fire extinguishing device to extinguish fires inside the vehicle. The T-72M4 CZ tank is a comprehensive upgrade of the T-72 tank to a level comparable to the 3rd generation tanks.

Perkins was bought by Caterpillar some time ago.


The important thing about the sights is that they are stabilized in both planes independently, i.e. the optical axis of the sight is the "master" and the gun is the "slave". In the T-72M1 this was not true in the sight (horizontal plane), there the cannon was the "master", so the image was "shaky" in the sight while moving.

The delay after adding throttle is due to the type of engine - it's a turbo diesel, so the turbos need a while to spool up and increase air pressure on the intake (from the intercooler), then there's an increase in torque and an increase in thrust.


The other factor is the hydrodynamic converter (basically a fluid clutch with a torque multiplier) between the engine and transmission. In the converter, 20 to 30% of the power (at large speed differences between the engine and transmission, i.e. under heavy load) is thwarted and converted to heat. The advantage of the converter, however, is that it reduces shifting shocks and thus saves the transmission.

so point by point.
The accuracy of the hit is not classified. or I know it (even officially), and I didn't have to sign anything about classified facts... where did you get the information that it is a classified fact?


yes, I didn't write the full official name of BVIS Smile


what exactly does the phrase sometimes live ammunition is used in training, but only in a limited way, although I don't think it makes logical sense, because the army disposes of the excess ammunition. does it mean that only the insert is fired?


and about the engine - I am not trained on the engine, so I only know this area casually... anyway, do you know from what rpm the turbo starts?
and the hydrodynamic converter... it is probably part of every automatic transmission... anyway, I would rather look for a gearbox, but an increase in speed in the terrain (more precisely, an increase in acceleration)

The turbo spins up depending on the characteristics given by the manufacturer. It's not explicitly stated that it will rev to exactly 1000 rpm, but it does vary depending on the power load. The mechanical composition of a given turbo will also come into play here. Some run a little better in the bearings and some run a little worse, so those revs vary again. But generally it's the 1000 rpm that counts.

I know how a turbo works, and the rpm it spins at on a regular engine... but I'm interested in the moment of turbo spooling on this Perkins....



so wait a minute, I just read your reply... so I guess I don't know how the turbo works... I thought it spins from a constant RPM... not from variables... so now I don't know...

On the probability of hit:
The numbers you mention are not correct. No army in the world publishes the actual hit probability, it's always a surprise to the adversary. If someone tells you these numbers or you read them somewhere it's just a lady telling you. After all, you can see for yourself if I'm right. According to the Freedom of Information Act you can ask the Ministry of Defence anything, try asking for the probability of a hit - see what they tell you.


Munitions:
By live ammunition I meant full calibre (125mm), not insert. The insert barrel is good for getting basic shooting habits, i.e. proper target tracking, proper aiming, operating tank firing equipment, etc. It is not a full substitute for actual shooting, however.


Engine:
Turbine blowers spin continuously because they are powered by exhaust gases. The faster they spin, the greater the air pressure in the engine, which positively affects the quality of combustion and therefore power. Their effect on torque is more noticeable from 1100 rpm (engine speed) onwards. Maximum torque is reached between 1500 and 1700 rpm with this engine.


Changer:
HDM is not part of every automatic transmission. There is a solution for the upgraded T-72 that does not have it.

takze bod po bodu.
presnost zasahu utajovana neni. resp ja ji vim ( i oficialne ), a nemusel sem podepisovat nic o utajenych zkutecnostech... odkud mate informaci, ze jde o utajovanou zkutecnost?


ano, nenapsal jsem cely oficialni nazev BVISu Smile


co presne znamena veta Občas se při výcviku používá i ostrá munice, ale pouze omezeně, i když logiku to myslím nemá, protože armáda nadbytečnou munici likviduje. je tim snad mysleno, ze se strili jen vlozkou?


a k tomu motoru - nejsem skolen na motor, takze tuto oblast znam pouze ramcove... nicmene, nevite od jakych otacek se roztaci turbo?
ad hydrodynamicky menic.. ten je snad soucasti kazde automaticke prevodovky... kazdopadne radsi bych ozelel razy do prevodovky, ale zvyseni rychlosti v terenu ( presneji receno alepseni akcelerace )




K pravděpodobnosti zásahu:
Čísla, která uvádíš nejsou správná. Žádná armáda na světě skutečnou pravděpodobnost zásahu nezveřejňuje, je to vždy překvapení pro protivníka. Pokud Ti někdo tato čísla řekne nebo si je někde přečteš je to jenom jedna paní povídala. Ostatně jestli mám pravdu se můžeš přesvědčit sám. Podle zákona o svobodném přístupu k informacím se můžeš dotázat na ministerstvu obrany na cokoliv, zkus se zeptat na pravděpodobnost zásahu - uvidíš co Ti odpoví.


Munice:
Ostrou municí jsem měl na mysli plnou ráži (125 mm), ne vložku. Vložná hlaveň je dobrá pro získání základních návyků při střelbě, tj. správné sledování cíle, správné míření, obsluhy zařízení pro střelbu v tanku atd. Skutečnou střelbu, ale plně nenahradí.


Motor:
Turbodmychadla se točí nepřetržitě, protože jsou poháněna výfukovými plyny. Čím rychleji se točí, tím je větší tlak vzduchu v motoru, což příznivě ovlivňuje kvalitu spalování a tedy i výkon. Znatelněji se na kroutícím momentu projeví jejich vliv od 1100 ot/min (motoru). Max. kroutící moment je u tohoto motoru dosahován mezi 1500 až 1700 ot/min.


Měnič:
HDM není součástí každé automatické převodovky. Existuje řešení pro modernizované T-72, které jej nemá.



mno, v dnesni dobe neco takovyho utajovat? kdyz vyrobce propaguje svuj tank kde muze? a my jsme soucasti jeho propagace? Jak rikam, mam na tento problem jiny nazor, vychazejici z jinych informaci...


stejne tak by me zajimal na zaklade ceho jste pronesl vetu, ze se k vycviku pouziva ostre munice ( tedy plne raze ) pouze omezene... muzete mi tedy prosim rici z jakeho zdroje mate toto info?


ad motor - dekuji.


ad HDM - muzete byt konkretnejsi ohledne te modifikace bez HDM?

As far as I know, the tanks have fired something like 70 rounds. Some more, some less, and there's also a production shot of about 20 rounds, so they have about 50 rounds a year, and I don't think that's much.

Citace - FearFac :

Pokud vím, mají tanky odstříleno něco kolem 70 ran. Některé víc, některé míň a je v tom i výrobní nástřel cca. 20 ran, takže odstříleno mají cca. 50 ran za rok a to myslím není moc.



muzu se zeptat ja primy zdroj teto informace?

Some of you has images or information about the battlefield managment system (BMS) installed on the T-72-M4 CZ? ......... TACTIS?


cheers

Do any of the members here have anything like reference images of the T72M4 in their photo archive? Or possibly some more accurate schematics including dimensional information?
Because I can't find any better quality photos anywhere especially of the upper hull, turret etc. It's similar with a schematic that could be modelled. Therefore I am asking a willing person for help.

Hello
On the 73rd Tank Battalion (Práslavice) website - www.73tankovyprapor.army.cz - the following is stated about the upgraded T-72M4CZ tanks:


"The M version tanks have been upgraded, so compared to the M1 type, they do not have the frontal armour of the hull and turret reinforced by ceramic cores."


I have searched through the photos of the T-72M4CZ on the internet to confirm or refute this claim. Unfortunately, the available photos are not sufficient for me to be able to identify the version from which the tank was upgraded - the dynamic armour shields, with one single exception, the photographers do not focus on the parts of the tank where identification would be possible.


But the one exception is here on the valka. cz server for the T-72M3CZ - in the detailed photo of the hull front there is clearly identifiable additional armour plate characteristic for the T-72M1 version (T-72M in the Czechoslovak army did not have it). Unfortunately, I am no longer able to determine if the turret also corresponds to the T-72M1 version.


If anyone has the opportunity to get a hold of a modernized T-72 try to photograph (maybe with flash needed) the lower part of the turret ring face - roughly the part that is just below the heavy dynamic armor. It is best to take more photos of that lower part of the turret - the T-72M1 has a characteristic armour bite (which is basically one of the basic distinguishing features). It is also possible to take a close-up of the hull front with the driver's hatch.


Greetings

Díky
Na té první fotce korby je jasně rozpoznatelné zesílené pancéřování T-72M1 (16 mm deska navíc oproti T-72M). Bohužel foto věže bych potřeboval ze spodu toho dynamického pancéřování (ne zeshora).


Jinak přikládám zpět foto korby s popiskem.

Martin thanks, but I meant to take a picture of the bite on the front of the turret - that is, to take a picture of it from the front of the turret (just below the cannon) directly under those dynamic protection blocks.


To clarify what I mean specifically, I am attaching two illustration photos (both originally from www.army.cz). The first one shows the T-72M1 with the beautifully visible bite we are looking for, the second photo shows the basic T-72 for comparison (it has the same turret as the T-72M, just without the smoke grenade launchers).


I am still wondering if the upgraded series includes both the T-72M1 and the T-72M (by the way, the AZ tank company of the ACR uses three variants of the T-72). Otherwise, I really don't understand why the original claim appeared on that site.

Pokiaľ sa na modernizáciu vyberali tanky na základe zostávajúcej životnosti, tak sa kľudne mohlo stať že modernizovali obe verzie.... (aj keď výmena dielcov pri modernizácii naznačuje že až na niektoré prvky by tam malo byť všetko vymenené).

If my eyes are not deceiving me, the last photo is the turret of a T-72M tank. Which leads me to another question (I know I'm getting annoying with this) whether the hull of this particular tank is reinforced or not. By the way, there was an intermediate variant introduced in East Germany - the T-72M1 hull with the T-72M turret, but it was never seen here and it was claimed that it was really just a German rarity ordered and made in Poland (and the Poles didn't introduce it either).


So it's possible that buko is right and both variants were modernized - for example the command modernized ones are from T-72MK, but that's just me shooting from the hip.


Anyway, thanks for the presented photos.
With regards

Hi
Thank you. It is a classic M tower (i.e. a basic cast tower without any "ceramics"). By the way, there is a recognizable hull from the M1 version. I have seen other M4CZs and everywhere there is a hull from M1 and a turret from M. I will add that from what I have seen, these are probably cast turrets of the second type, i.e. the rounder ones and the most widespread in our country (the rounder variant of the basic cast turret was probably not produced in our country at all and only a few such turrets were imported initially).

Very nice and informative article! However, I would like to ask one thing about the tank T-72. My question relates to the starting system of the engine of the tank. On the page LiveLeak.com I found this video http://www.liveleak.com/view?i=4c1_1377519180 - (I'm not author of this video, all copyright belongs to its authors). The video describes the procedure of starting of the engine of tank T-72. I would be glad if anyone could accurately describe the action taking place in the video. For example, what exactly does the tank starts. From the video it is not completely clear. Since I'm a big fan of military technology, these things made me very interested. I assume that the starter could be somewhere in the picture with the name cz3.jpg on page 1 or somewhere next to that panel because there is also a lever of the electrical generator, which is to start the engine essential. Thank you in advance for the answer..
