During a discussion at the Aspen Security Forum on Friday, Army Gen. Raymond Thomas, head of US Special Operations Command, cited estimates saying that the US-led fight against ISIS had killed 60,000 to 70,000 ISIS militants.
It is not the first time US military officials have given estimates for ISIS body counts — Thomas himself cited a similar number in February — but those estimates have been made despite doubts among military leaders and government policymakers about their accuracy and usefulness.
When asked about the whereabouts of ISIS leader Abu Bakr al-Baghdadi, Thomas downplayed the ISIS leader’s influence and said that while Baghdadi’s fate is currently unknown, “we will get him eventually.”
To underline his point, Thomas elaborated on the damage done to ISIS’ personnel network.
“I mean, everyone who worked for him initially is dead or gone. Everybody who stepped to the plate the next time, dead or gone,” Thomas said. “Down through a network where we have killed in conservative estimates 60,000 to 70,000 of his followers, his army. They declared an army, they put it on the battlefield, and we went to war with it.”
Those comments come several months after Thomas claimed that more than 60,000 ISIS fighters had been killed since the campaign against the group started in summer 2014.
“I’m not into morbid body counts, but that matters,” he said in February, speaking at the National Defence Industrial Association’s Special Operations/Low Intensity Conflict conference. “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.”
Body counts — which earned scorn during the Vietnam War — are considered a dubious metric by which to measure the success of a military campaign, particularly ones against groups like ISIS. It is typically hard to estimate how many fighters such groups have, and it is not always clear how many have been killed during military engagements.
In 2014, an observer group estimated the terror group had 100,000 fighters. The Pentagon said in summer 2016 that it had just 15,000 to 20,000 fighters left in Iraq and Syria.
The February number given by Thomas was not much higher than the 50,000 ISIS-dead estimate made by US officials in December. But the December number given by US officials was twice as high as the figure cited by UK Defence Minister Michael Fallon that same month.
And the figure cited by Thomas on Friday was only slightly higher than what he said in February, despite the increased intensity of anti-ISIS operations in Iraq and Syria in the intervening months.
Air operations against ISIS in Iraq and Syria increased significantly after Trump took office in January, with military leaders emphasising an “annihilation campaign” aimed at eliminating ISIS fighters.
But those air operations appear to have caused a considerable increase in civilian deaths.
The US government reversed its policy on body counts several times during the wars in Iraq and Afghanistan, and numbers given by the government have been undercut or criticised by civilian and military personnel alike.
“My policy has always been, don’t release that kind of thing,” Chuck Hagel, who served as secretary of defence from 2013 to 2015, told CNN in December 2016. “Body counts, I mean, come on, did we learn anything from Vietnam?”
