Military deception, counter deception and online warfare - Part 2: Red Teaming and Counter Terrorism (Drop 1 of 2)

This Drop is a follow up to the very first drop I ever posted to this page, on the use of tactical military deception by western armed forces and how those tactics are used on us?

Military deception, counter deception and online warfare - Part 2: Red Teaming and Counter Terrorism (Drop 2 of 2)

This 2nd drop, will focus on the counter terrorism side of the Red Teaming concept and the original reason for why Red Teaming became a training practice of the military, to the virtual standard operating procedure it is now, when concerning counter terrorism units and their continued justification for existing?
