Battleground: Rhino Wars (2013)

A war is raging just outside Johannesburg, South Africa. Each year, nearly 700 rhinos fall prey to poachers over the commercial demand for rhino horns, an exotic commodity more valuable than gold. With park rangers being murdered trying to protect the wildlife, former U.S. Special Operatives go on the front lines to help defeat the poachers before the rhinos become extinct.
