Two elephants walk through the Rungwa Game Reserve in Tanzania July 24, 2016. Tanzania Park and Game Reserve rangers have recently received training from the North Carolina Army National Guard and the 403rd Civil Affairs Battalion, a component of Combined Joint Task Force - Horn of Africa, on how to capture poachers hunting the animals. Poaching and trafficking in wildlife has become a source of revenue for violent extremist organizations on the continent. (Courtesy photo provided by Army Sgt. Billy Allen.)
