ANCHORAGE -

An Alaska Army National Guardsman is in stable condition after being mauled by a brown bear sow during a Sunday morning exercise on Joint Base Elmendorf-Richardson.

In a statement on JBER's Facebook page, base officials say the incident was a product of "an encounter with a brown bear sow defending her nearby cubs during a land navigation exercise in a training area" on base.

The Guardsman is being treated at the base hospital.

JBER officials referred questions to Alaska National Guard spokesperson Maj. Candis Olmstead. A call by Channel 2 to Olmstead's cellphone wasn't immediately answered Sunday afternoon.

In May, Jessica Gamboa was running with her soldier husband when she was mauled by a brown bear on base, in an incident JBER officials described as a "'wrong time, wrong place' situation." Gamboa later said she thought she would die in the attack on the Fort Richardson side of the base, before the sow that attacked her ran away and Gamboa was able to reach medical attention.

Anyone who sees a bear on base is asked to call JBER's Conservation Enforcement office at 552-8609 or 552-9453.
