Lets just say that the Indian Army was rather disappointed with the T-90's primary armor when compared to the Arjuns, I got a feeling that you are going to see alot of technology advancements from DRDO's armor programs getting passed on to Indian T-90S and T-72 series. Too many people out there have only focused on the negatives versus the positives when it comes to DRDO's progress in certain areas.
To my Indian friends;
I have heard that Israel is giving a big hand in regards to tank projectiles, whats the word on the streets, anything being printed in India with regards to this.
