Hi lady, first of all, we need to define what is "off grid" for the military...
1. if off grid means having your own generators and electricity to operate your equipment...they have been that way since the late sixties. All military rocket launchers, laser rangefinders, computers and GPS systems need to be re-chargeable and or solar-chargeable. Very few soldiers can even read an old map with coordinates any more.
2. if off grid means no longer depending on the standing electrical grid available to us "common" folks, then they are making fools of themselves. If any grid goes down, then it goes down for ALL...and only the Rangers or Special Forces get real survival training.
3. if off grid means being able to LIVE, FIGHT, WORK AND SURVIVE without electricity...the WOKE and the AWAKE will have the same problems we "common" folks have and will have more trouble to survive than us because we are ready and used to having the grid go down with tornados, hurricanes and wildfires already....
Do not worry about the hear-say of such training and worry MORE about why the ARMY has been acquiring and training soldiers how to use portable GUILLOTINES...seen on a now no-longer-available-video...
