The nearly two dozen soldiers injured in a “helicopter mishap” in northeastern Syria were members of an elite commando unit known as Delta Force, according to The New York Times, which cited three senior military officials. The highly secretive group has carried out a number of dangerous raids against Islamic State militants in the country over the past few years, the Times reported. The United States Central Command (CENTCOM) said in a statement that the injuries were of “various degrees,” but did not provide more specific details of the troops’ condition. “The service members are receiving treatment for their injuries and 10 have been evacuated to higher care facilities” outside of CENTCOM’s area of responsibility, officials said. “The cause of the incident is under investigation, although no enemy fire was reported,” the statement added.
