Elite service members from four branches of the U.S. military will launch an operation this summer in which they will operate covertly among the U.S. public and travel from state to state in military aircraft. Texas, Utah and a section of southern California are labelled as hostile territory, and New Mexico isn't much friendlier. That's the scheme for Jade Helm 15, a new Special Operations exercise that runs from July 15 to Sept. 15. Army Special Operations Command announced it last week, saying the size and scope of the mission sets it apart from many other training exercises. The exercise has prompted widespread conspiracy theories that the United States is preparing to hatch martial law. In particular, some have expressed alarm about this map, which outlines events for the exercise in unclassified documents posted online last week. The Washington Post verified them to be legitimate by speaking to Army sources. They appear to have been prepared for local authorities. It's also worth noting that the military has routinely launched exercises in the past in which regions of the United States are identified as hostile for the purpose of training.
