OFB did what was told that`s how things works..
OFB studied the casspir MPV when bought from SA, And its known abt the need and Imported price tag, So the order goes for manufacturing Similar MPV in India, When this DRDO 4x4 was proposed to Paramilitary at that time MPVs were operational and proved good against mines and were good on ground..
Further money spending was not in option for DRDO 4X4, But its always their for export..
Now, If someone think same as me can say the requirements and things would be done right away, But that`s just me..
