Armored Threat and Threatened Armor The desert is a harsh environment, testing warriors and their armor; yet when the U.S. Marines fire and maneuver, they often find an armored friend - the threatened Desert Tortoise - already holding the high ground. The Marines, with the help of the U.S. Fish and Wildlife Service, are working to protect endangered species while maintaining military preparedness. One result: at Twentynine Palms, both armored threat and threatened armor are ready for the future. That's what happens when some of your best friends are Marines.
