JOINT BASE LEWIS-McCHORD, Wash.—The Army says firefighters have rescued three paratroopers who got stuck in trees after they jumped from an aircraft in a training exercise in Washington state.

Joe Piek (PEEK') is a spokesman for Joint Base Lewis-McChord south of Seattle. He says all three were unhurt after getting stuck in trees near one of the base's drop zones on a windy Thursday afternoon.

He didn't have many details but says the big, wide-open drop zones are surrounded by trees, and parachutes can drift off course if winds change or increase during a jump.

Piek says firefighters from both Thurston County and the base responded.

The rescue took place in a thickly wooded area near the town of Rainier.
