KOMO-TV reports the attack happened around 8:30 a.m. on Saturday on the base near Tacoma, Washington. Officials said the man, a civilian, was attacked while walking in a restricted area. He sustained only some scratches.
Officials are now looking into why the man was there. They're also looking for the animal that attacked him.
Bears are common in the area. In April, Washington state wildlife agents shot and killed a black bear at the base, a week after a bear attacked a civilian base employee. That employee, who was attacked while he was running with his dog on the base, was treated for non-life-threatening injuries.
