The first batch of five indigenously built Arjun Main Battle Tanks formally rolled out of the Heavy Vehicles Factory at suburban Avadi near Chennai today.

Describing the event as a red-letter day, Defence Minister Pranab Mukherjee said that India should be equally vigilant and determined not to secede even one millimetre of her land though the country had no territorial ambitions. India was not keen on annexing any territory or expanding her territory, he said.

Army Chief Gen N C Vij said India was keen to have less dependence on importing tools of warfare.
