Singh claims in the book that the NSA had asked then Army Chief Deepak Kapoor if the Army could create an organisation with covert capability to hit back at Pakistan but Kapoor was not receptive to the project.
The proposal was then made to him by the then Director General Military Intelligence Lt Gen RK Loomba, he writes in the book.
The intent was to increase the scope of the proposed intelligence unit to have tentacles in neighbouring countries and surrounding areas, the book says.
The unit has been mired in controversy after allegations were levelled against it that it was involved in snooping the telephones of important officers in the Defence Ministry and carrying out unauthorised operations in Jammu and Kashmir against the state government there.
