A little over two years ago, a combined assault force comprised of Delta Force and Special Air Service operators went after an ISIS high-value-individual (HVI) somewhere in Syria. As the commandos neared their objective, an improvised explosive device (IED) went off killing one American and one British operator.

The consequent investigations by the U.S. and British militaries, however, suggested that the deaths were a result of friendly fire. For those in the know, the investigations fingered Master Sergeant Johnathan Dunbar, the Delta operator killed, as the perpetrator. SOFREP, however, learned that wasn’t the case. Here is what we found. 

The British Ministry of Defense (MoD) released the results of an internal investigation last week regarding the deaths of Special Air Service (SAS) Sgt. Matt Tonroe and Delta Force Master Sgt. John Dunbar during a high-value target operation in Manbij, Syria, in March of 2018.

The report retracted the original cause of death, which was given as an Islamic State improvised explosive device (IED), and stated that the two commandos had been killed by friendly fire. The U.S. Special Operations Command (USSOCOM) echoed both the original MoD statement and the results of the internal report.
