Russian T 72B base armour is thicker made of composite ( super dolly parton ) is different from the one in export variant which were thinner aka monkey models including one sold to india. ERA MK2 is same as K 5. T 72B has better gun ( 2A46M-5) & better ammo ( svinets 1 & 2 ).
The base armour of t-72 is almost 50 years old design
There zero evidence support your claim.
Geez !!!Now don't start making up things
Firstly you have no idea what your talking about so your start making up random stuff.
T-72B is upgrade of older stocks of Soviet era T-72
With Kontakt-5 ERA panel Gun upgrade and thermal sights
And better engine started in 2010
The T-72 base design has same thickness for every variant sold outside.
The only difference is Kontakt-5 ERA panels
And relikt ERA for T-72B3 M
"T-72B3 (Ob'yekt 184-M3): this upgrade was initiated in 2010 using old stocks of T-72B tanks held in reserve. In addition to performing a general overhaul of every vehicle, certain tanks were equipped with the more powerful V-92S2 engines, a new steering system in the driver's compartment and older tracks were replaced with the new universal, twin-pin design. The upgrade program focuses instead on improving the tank's firepower, mainly through the implementation of the Kalina fire control system, albeit in a simplified form. The tank commander retains an upgraded version of the legacy TKN-3MK sight, which is a passive device with a range of only 600 m at night, but is augmented with a monitor that displays thermal imagery from the gunner's main sight. The commander also has a new turret control panel. The gunner still has the 1A40-4 FCS with 1K13-49 sight, but these are now part of the auxiliary sighting system to complement the new PNM Sosna-U panoramic multi-spectral sensor, which replaced the TPN-3-49 in its mounting. The Sosna-U is a multi-channel, panoramic sight stabilized in both vertical and horizontal axes with a built-in laser rangefinder and command guidance module used with 9M119M missiles. The most advantageous aspect of the Sosna-U is the Thales Catherine-FC thermal imager which extends the detection and identification range of a tank-sized target to 10,500 m and 3,300 m respectively, at night/day and in all weather combat conditions. The T-72B3 series vehicles also received the new 2A46M5 main gun which has a dispersion value significantly lower than previous generations,"
ERA MK2 is more modern design based on
Indian research on "Kachan armour" and Kontakt-5
It has better quality compared to
Both that is Published in DRDO magazine
Based on Field evaluation results
It's has peer reviewed and Published research papers.
As For ammo
India already has Israel or Russian Mango APFSDS or DRDO
Indigenously developed which can
Has 550mm penetration.
Right now DRDO Is developing APFSDS of 700-800 M penetration class
Compare R&D spending of India and availability of western technology to India.
That made us self reliable in radars, missiles,
Submarines technology.
Days of Russian dominance passed
India has now access to technology which
Russian only dreams about
Like Rafale F3R
Probably the most modern Fighter than any Russian has there inventory with Meteor BVR.
