Jade Helm 15 conspiracy theories

The Jade Helm 15 conspiracy theories were based on the Jade Helm 15 United States military training exercise, which took place in multiple U.S. states between July 15 and September 15, 2015. The exercise, which involved 1,200 personnel from four of the five branches of the U.S. military, was designed to train soldiers in skills needed to operate in overseas combat environments, including maneuvering through civilian populations.
