More than a dozen Army Rangers are claiming suspicions that two soldiers were killed by friendly fire in Afghanistan are "100 percent false," according to a report.

The Pentagon said Friday morning that it has launched an investigation into whether to the two Rangers — Sgt. Joshua P. Rodgers and Sgt. Cameron H. Thomas — might have been killed by fellow U.S. or allied Afghan commando ground forces during a raid to kill a top Islamic State leader in Nangarhar province.

But a group of soldiers who spoke to Task and Purpose were part of a task force with direct knowledge of the raid, which included 50 Rangers and 40 elite Afghan troops, according to the website.

"This is tainting the memory of the fallen with unneeded controversy," one of the Rangers told the site.

The Pentagon declined to comment on the report because there is an ongoing investigation into the incident.

The joint U.S.-Afghan force waged an intense three-hour firefight during the assault on a fortified ISIS-Khorasan compound less than mile from where the Air Force dropped its so-called "mother of all bombs" this month to destroy an ISIS tunnel complex, according to details provided by the Pentagon.

The assault included airstrikes and support from an AC-130 gunship, Apache attack helicopters, F-16 fighter jets and drones, according to the Pentagon.

The raid killed 35 ISIS-Khorasan fighters and likely took out Abdul Hasib, the group's emir of Afghanistan and a top U.S. target.
