An appropriate use of Signal:
Group, we need to discuss something in the SCIF. Please report to the closest SCIF to discuss. Urgent.
An inappropriate use of Signal:
Group, we’re going to bomb the shit out of the Houthis. The sequence of events goes like this…we’ll use this type of weapon, we’ll be going after so and so, then we’ll have HUMINT battle damage assessment and then use xyz weapon to take out abc targets at 0200 on xx date.
Sure, that’s appropriate. NOT!
