They've already been using Signal - which is "commercial" app, meaning it's not meant to be used like that - for top-secret (or at least highly sensitive) military communications during the military strikes on Yemen. If that was fake, I apologise, I was deceived. I wouldn't be surprised if things turned out that way again, to be honest. That's something to be expected, actually (IMO).

The legal name of the department is still the Department of Defense. The "Department of War" is a preferred name by the administration.

They are after the models without post training guardrails.
