I was a soldier for 26 years or so. Signal. While stationed at Ft Carson (Colo Springs) in the early 80's, we would go "down range" on Fort Carson and do training exercises. The Infantry brigades would sometimes come and sometimes it was just us. We got so good that we didn't need maps anymore, we called all our locations by name like Saw Tooth Mountain, Agony, Misery and Artillery Hill and so on.
We got permission to do an exercise in the Rocky Mountain National Park, and that was really cool. Had to do recon, site survey, mapping and so on, as well ans perfect our spark arrestors on our generators and all our vehicles. We had to practice "zero impact" on the National Forest ecosystem. We got to practice lots of things for our intended mission of war in Germany against the (then) Eastern Bloc.
Nothing nefarious about it. I have trained in the Utah desert, the Georgia mountains, Arkansas, Colorado, Texas, California, New York and Florida. Most of it on post, but then some of it not on post.
I've never worn a tin-foil hat, but I wore a steel and later a Kevlar helmet, ate a lot of C's and MRE's, and even taught National Guard and Reserves "crowd control" while I was a Drill Sergeant.
But I've never ever gotten the feeling that my Army would ever march against American Civilians.
Here is aquote from one article I found with Google:
“You’re going to have thousands of troops here buying groceries, and the military’s going to be buying fuel in the area,” he said.
Army Special Operations Command representatives could not confirm if Jade Helm personnel will purchase supplies locally."
To think that "... thousands of troops here buying groceries.." tells me whomever wrote that knows nothing at all about military training.
But if it bother's you, I hear the Canadian borders are still open.
