Revenue service officers drawn from the Enforcement Directorate, Income Tax, Serious Fraud Investigation Office, Directorate of Revenue Intelligence and CBI are being trained by premier agencies, including Research and Analysis Wing (RAW) and the Intelligence Bureau in ‘intelligence tradecraft’. There are nine course modules developed for the officers to acquire expertise in intelligence gathering and handling of digital and forensic evidence. The courses at RAW’s training academy at Gurgaon and IB’s National Intelligence Academy in Delhi have been restricted to only Group A officers of the Indian Revenue Service. However, other modules are open to officers starting from superintendent level up to principal commissioners.
