Crew skill matters, but they still can only operate within the parameters that the equipment allows. The 2A46 gun, combined with the gunners sighting devices on a T-72 simply do not allow for extremely precise shots on things like hatches except at very, very short ranges. It would be like expecting someone with a rifle to be able to hit a match point 5 km away, it's just not going to happen absent a very large amount of luck.

Teaching this strategy has never, that I am aware of at least, been taught as any type of actual strategy in armoured warfare. This should indicate how reliable it is since the areas that numbers mentioned are indeed quite vulnerable and if it was possible to consistently put rounds through these vulnerable locations then I have no doubt that it would be S.O.P. However, the fact that it's not does seem to indicates that it's not possible. The upper level of what seems to be achievable with the current levels of technology (to say nothing of 1960s/1970s technology) is being able to hit general areas of a tank such as the side of the turret, skirts, that sort of thing. Even aiming at things like bustles is extremely risky and from what I have read, unlikely at best.

The image above should be confirmed by the T tower 72.
Modern tanks can only be successfully attacked from above.

Would it be too costly for Iran to produce its own T-72s?

Why doesn't Iran develop such industrial infrastructure?

I would think such manufacturing achievements in many ways could be valued more than being forced to buy everything made abroad.

I think if Tank has to make smoke and withdraw then it is loosing it's own ability to fight and becoming useless . Unless  it makes smoke and advance under cover of smoke to get close and shake hand of other tanker . A T-72 can use smoke but NOT like the Leclerc tank  ( special smoke ) when it spot M1A1 . Not to escape but to advance and get close to it . For example if it see M1A1 from 4000 meter away , and it is closing in on it at 30 km/hr , it then takes 7 minutes to reach it's  maximum shooting position of 500 meter with Kornet laser guided .

( 500 m/minute for 7 minutes = 3500 meters ) . In this time it can use smoke round to blind the M1A1 tank , by putting the round NOT close to itself , BUT  putting the round(s) say 100 meter in front of M1A1 tank to blind it . If M1A1 is also going  to meet T-72 at 10 m/sec , then in 10 second it travels 100 meters and will not break through the smoke screen . ( This supposes that T-72 is firing 10 smoke rounds per minute ) .

Once T-72 in position to fire from 500 meters , and guide the Kornet to target . If M1A1 use smoke to hide then this gives T-72
chance to hit it with heat round . If M1A1 is using active armour , then special round ( anti-radar) can be launched first  and this will create anti-radar cloud and allow T-72 to hit again with heat round . The M1A1 is disabled at this time by own smoke and can not fire back . If M1A1 stop smoke screen , then T-72 use Kornet again .If smoke then close in further .

If M1A1 use similar tactic and use smoke to blind approaching T-72 , then this is not a problem . Because smoke rounds do not have to be accurate and can be launched in general direction of M1A1 with good effect . Can be launched like Howitzer from 4000 m away very accurately .

If Iran uses a TV guided Toophan (TOW ) wire guided full of anti-radar particles and fires a salvo of follow up Toophan  that are both wire guided and IR guided ( from AFV's multiple launcher ) , then first TOW has a good chance of breaking through the defensive smoke screen of M1A1 and disable radar . The follow on Toophan can follow each other's IR signal like Berbeque and hit the same spot . First Toophan destroys the passive armour and second one or third one punch through the same spot . Multiple launches of Kornet are already done . Other systems can be cheaply developed . With available computers and sensors .

Now if two T-72 attack one M1A1 , then each need only 35 smoke round and the rest is Kornet . Also if T-72 has wind on it's back when it attack and if smoke is designed to stick to optic and glass and periscope then M1A1 is made useless early on .

Yes IR is more problamatic ! But we can use anti-IR smoke as listed below . Otherwise attack from hidden position . If T-72 can hide in hole at bottom of koohpaye near a path or valley then it can jump out and attack as you said . Also dispersal of small aerosol particles can be done in the same round . If for instance small plastic powder is mixed with white phosphor shell then heat melt plastic and it stick to glass ! T-72 need carry smoke and Kornet and heat round together .

The proliferation of thermal imaging FLIR systems on the battlefields necessitates the use of obscurant smokes that are effectively opaque in the infrared part of electromagnetic spectrum. To achieve this, the particle size and composition of the smokes has to be adjusted. One of the approaches is using an aerosol of burning red phosphorus particles and aluminium coated glass fibers; the infrared emissions of such smoke curtains hides the weaker emissions of colder objects behind it, but the effect is only short-lived. Carbon (most often graphite) particles present in the smokes can also serve to absorb the beams of laser designators. Yet another possibility is a water fog sprayed around the vehicle; the presence of large droplets absorbs in infrared band and additionally serves as a countermeasure against radars in 94 GHz band. Other materials used as visible/infrared obscurants are micropulverized flakes of brass or graphite, particles of titanium dioxide, or terephthalic acid.

Older systems for production of infrared smoke work as generators of aerosol of dust with controlled particle size. Most contemporary vehicle-mounted systems use this approach. However the aerosol stays airborne only for a short time.

The brass particles used in some infrared smoke grenades are typically composed of 70% copper and 30% zinc. They are shaped as irregular flakes with a diameter of about 1.7 µm and thickness of 80-320 nm. [1]

A dry powder fire extinguisher is said to be a good improvised system for production of aerosol effective even in far infrared. [2]

Some experimental obscurants work in both infrared and millimeter wave region. They include carbon fibers, metal coated fibers or glass particles, metal microwires, particles of iron and of suitable polymers. [3]
