FORT HUNTER LIGGETT, Calif.-- Authorities say 22 soldiers were injured in a tent collapse at a Central California military base Wednesday night.

The Fort Hunter Liggett Facebook page says wind from the rotors of an Army UH-60 Blackhawk helicopter that was landing blew over the tent during a training exercise at a remote area of the base.

Base spokesperson Amy Phillips says there were 22 injuries, most of them minor. She says four people were taken to hospitals. Earlier reports said up to 30 people were injured.

Fort Hunter Liggett is in Monterey County, about 170 miles south of San Francisco. The sprawling base is the largest U.S. Army Reserve Command post.

It's currently holding an annual training exercise for thousands of Army, Navy, Air Force, Army National Guard, Army Reserve and Canadian Armed Forces troops.
