The Army says that at around 9:30 pm Wednesday, a Blackhawk helicopter landing in a remote training area kicked up wind that caused a tent structure to collapse.
At least 22 soldiers were injured in the collapse, two of the injured were flown to the trauma center at Community Regional Medical Center in Downtown Fresno, while two others were taken by ambulance to a hospital in Templeton. The rest of the injured were treated on site.
Officials at the base say that there are no reported fatalities, but that they are still gathering information.
Fort Hunter Liggett is located about an hour northwest of San Luis Obispo and is primarily used as a training facility, where soldiers learn maneuvers and participate in live fire exercises. The sprawling base is the largest U.S. Army Reserve Command post.
A training event was being conducted at the Fort at the time of the incident. Officials say that it is an Army Reserve training exercise called a Combat Support Training Exercise. Thousands of Army, Navy, Air Force, Army National Guard, Army Reserve and Canadian Armed Forces troops are participating in the exercise.
