How credible is this? Who wants some old Indian T-72 tanks?
Any old T-72 from India is most likely gonna be trashed and dirty. I don't think it's wise to trust the Indian "upgrade and refurbishment" work. Chances are, those tanks are not gonna drive for long. Better for those tanks to go back to Russia for restoration, or just prepare to scrap them. Nevertheless, if anyone is looking for bargain T-72s, and couldn't care less about their condition, this might be decent deal.
India might also start selling their old BMP-2s in the future. Good luck to anyone who is gonna buy them and ride in them.
They can technically return it to Russia or sell them to Ukraine.
