Common questions
When does NSG SAG get called in over a local bomb squad?+
Local or state bomb disposal units typically handle routine or lower-threat devices, while NSG SAG is mobilised for major terrorist incidents, complex or suspected IEDs, or high-profile targets where specialised national-level capability is warranted.
What forensic role does the unit play after making a device safe?+
Beyond neutralising the immediate threat, the team preserves and hands over device components, residue, and other post-blast material in a state suitable for CFSL and NIA forensic examination and case-building.
