Also TATRA is expensive bu not sub standard. If it was why it is in the service of armies around the world including KSA & Israel.
The allegation was that many of the spare parts that came with it were defective, they did not have a maintainance facility in India (due to which czech technicians had to be brought each time), and SOME OF THE BATCHES sold to india through BEML were sub-standard. Not that the platform is substandard as such.
Also, there is no excuse for BEML buying it from europe for 40 lakhs and selling it to the army for twice or thrice that amount.
