Jade Helm 15, the controversial Special Operations exercise that spawned a wave of conspiracy theories about a government takeover, will open next week without any media allowed to observe it, a military spokesman said. Embedded reporters won't be permitted at any point during the exercise, in which military officials say that secretive Special Operations troops will maneuver through private and publicly owned land in several southern states. The exercise is scheduled for July 15 through September 15 and is expected to include more than 1,200 troops. Army Special Operations Command announced the exercise in March, saying its size and scope would set it apart from most training exercises. For months, some protesters have said Jade Helm is setting the stage for future martial law. Texas Gov. Greg Abbott, a Republican, called in April for the Texas State Guard to monitor the exercise [to] improve communication between Special Operations forces and civilians in Texas. The Washington Post has several times requested access to observe the exercise, making the case to the military that first-hand media coverage would help explain the mission. [Army spokesman Lt. Col. Mark] Lastoria said it is not possible to allow a journalist to travel with Special Operations forces in the field. The military has granted access to Special Operations in the past, however. In one recent example, a journalist observed the exercise Robin Sage in North Carolina.
