"Stop gaps" that doesn't make sense. T 90ms are expensive and capable tanks. They will serve IA for decades. Are you assuming them t 90s will be retired ASAP, when new Indian tank design comes along.They are ordering a batch of Arjuns, along with the T90MSs. Both are not India's future armored solution regardless, both orders are rather stop gaps.
It's shocking how poor the ammo is. I assumed ammo storage was protected and had blow out panels like m1 abrams. Massive weakness on the front. Mk2 is gonna have reduced mobility due to extra weight.
