Maybe. But I will point out that locals are warned this will be a noisy affair, with combat noise. I doubt military units need need combat training in how to engage against a local police force. And I doubt our police need training in how to fight against an invading military force.
This is being done with secrecy. There are two reasons possible for that. Training they don’t want an enemy to know about, or training they don’t want US to know about. Too many things are called secret, not because of an enemy, but because they don’t want public attention.
I don’t trust secrecy when it comes from police. When they go covert, it is for their good, not ours.
Can’t argue with that. A lot has been happening that is quite - well - strange.
