The Army says the size and scope of Jade Helm 15, a Special Operations exercise that begins in July, set it apart from other training exercises. Also setting it apart: The widespread conspiracy theories that the U.S. is preparing to hatch martial law. The Post's Dan Lamothe explains. (Tom LeGro/The Washington Post)

As debate and conspiracy theories continue to percolate about the new military exercise Jade Helm 15, Checkpoint has been asked to help explain what the operation is — and is not.

Above, a video providing some context on the mission. As previously covered here, Jad Helm 15 is expected to span a good portion of the summer in a number of southwestern U.S. states, including Texas, California, Utah, Colorado and New Mexico. About 1,200 Special Operations are expected to participate as they prepare for potential operations overseas, according to U.S. military officials.

In addition, I appeared this morning on C-SPAN’s “Washington Journal” to discuss Jade Helm 15 and take calls from viewers. You can watch that here:
