that the Arjun is a more heavily armored tank than the T-90. Just because you are ignorant, and abusively so, does not make your Russian fanboy'ism any less ignorant.
1) maybe in hull. Not in Turret, becouse this is shitty in Ajrun MK.1. It's look like rejected turret project Leoparda2A0 from the mid-1970s.
2) You should know that, we in Poland rather don't like russia. And only Poland and Finland have trully comparison beetwen western and estern tank (T-72M1/PT-91 and Leopard2A4). End we have IMI technology in Poland. for example: two of Israeli turret from APC's (UTD-30/RCWS-30) were rejected after testing - because it does not work below 20 degrees below zero. As I said we have 125mm IMI rod's in Poland in PRONIT 125mm APFSDS. Over 20% of cores did not keep their performance at low temperatures, and penetration is mucht mucht less then 500mm RHA.
After that polish industry has teamed up with Germans - the result is "squeezing" of more than 600mm 125mm APFSDS penetration for new Polish 125mm APFSDS. But he is no longer required - the future of the Polish Army caliber is 120mm.
BTW: more then 14% Spike ATGM for Poland have manufacturing defects and crashes after take-off.
This is the topic of quality weapons from Israel.
So writing that clone 125 mm IMI is better than 3BM44M looks rubbish. In Poland, we tested these "Jewish miracle" - sorry, we prefer to cooperate with the Germans.
New Polish cores are copies of those from Germany - of course adapted to the shorter cartridges, and not as new as DM53/63. But it was enough to achieve more than 600mm (~ 600-610) of 125mm cartridge.
The oldest ones (120 and 125mm sabots/rods
Old "pronit" and New APFSDS. On the photo is only "old" PRONIT. New sabot is in the table of course photo should be not placed in internet, so sorry ;-)
BTW:
There are no Russian rounds available for export right now which match the latest israeli rounds.
As I said - this "latest israeli rounds" is SHITTY. As many other weapons form Israeli.
Of course they try to change it - if You in Idnia thrust them (IMI) - good bless
They just lie about their (Jewish) wepons performance. Soory, we had this ~5-8 years ago in Poland. The Russians are doing the same thing - overstate the performance of weapons. But there are NOT worse than Jews.
