If indigenous system is already available from drdo/l&t then what is the need of even considering foreign system.
Rest Every country give full commitment to their indigenous systems only here these dalal generals are running the shit show so that they can get commission.
Yeah, it's unclear why there are 2 different tanks. I guess the requirements for both types are different.
Anyway, you are overestimating the Indian defence industry. The industry still needs until 2030 for it to mature. Right now, most of their products are something only the Indian forces will clear for use after extremely extensive trials. They cannot yet compete with more seasoned international companies. For example, when an Indian company says this or that is the most tested, what they are actually saying is their product has failed so many times that it had to be tested multiple times for clearance.
And no, generals earn more money from local companies and indigenous equipment. Foreign companies don't bribe as much as you think. And it's DPSUs that do the most corruption, hence one of the reasons for the lack of trust in them by the forces. Most of the stealing happens outside procurement, mostly maintenance and logistics.
