Gen. Raymond Thomas, head of US Special Operations Command, said on Tuesday that the US and its allies in the fight against ISIS had killed more than 60,000 of the terrorist group’s fighters.

That estimate was considerably higher than the 50,000 ISIS-dead estimate given by US officials in December.

Thomas, whose command includes Navy SEALs and the Army Special Forces, was cautious in his remarks but held up the total as a sign of the anti-ISIS campaign’s impact.

“I’m not into morbid body counts, but that matters,” he said, speaking at the National Defense Industrial Association’s Special Operations/Low Intensity Conflict conference outside Washington, DC.

“So when folks ask, do you need more aggressive [measures], do you need better [rules of engagement], I would tell you that we’re being pretty darn prolific,” he added.

The increase between December and now may be attributable to stepped-up campaigns in Mosul, Iraq, and Raqqa, Syria, but body counts are generally considered a dubious metric for a number of reasons.
