In public assessments of drone strike casualties during the Obama administration, authorities assumed that any male of military age was likely a combatant. The New York Times, first reporting the policy in 2012, noted that exceptions were made when "there is explicit intelligence posthumously proving them innocent."
Nicholas Grossman, a University of Illinois international relations professor, said the practice systematically underestimated civilian casualties. "Essentially, this assumes that any man (or boy) in the vicinity of a known terrorist who appears to be between the ages of 14 and 60 is also a terrorist," he wrote.
The Trump Administration revoked the rule requiring regular disclosures in March 2019.
