The types of munitions used and their characteristics would be factored into the Supplemental Assessment which would take the Initial Assessment and layer intelligence inputs from other sources. This would include SIGINT from NTRO[20] which had helped confirm 300 active mobile connections at Jaba Top in the days prior to the attack. Depending upon NTRO’s capabilities, if all or most of those active connections went dead after the attack, that would be a strong indicator. HUMINT from R&AW and IB, and IMINT from our own satellites and from friendly countries would play a crucial role in forming the Supplemental Assessment. It would also incorporate Open Source Intelligence (OSINT): accounts like the one by journalist Francesca Marino whose sources confirmed that the death toll at Jaba Top was between 40 to 50 and included JeM trainers and bomb experts and retired Pakistan Army officers[21]; the February 28 audio clip from the JeM event at Peshawar where the terror group acknowledged the attack on its camp[22], etc.
