“Rapid dominance attempts to affect the will, perception, and understanding of the adversary to fight or respond to our strategic policy ends through imposing a regime of Shock and Awe” (Ullman & Wade, 1996)

One could argue that “shock & awe” is a military strategy to specifically terrorize the enemy force, for example a military opponent. This would blur the line above (terrorism vs military) as it intends to affect the opponents minds with fear of the attacking group and thus coerce them away from their goal.

This strategy is one performed by an organized military that is (theoretically) bound by the rules of warfare (like the Geneva Convention) and unlawful acts can be prosecuted by either their own military law system or an international court (like the Hague). Non-state actors (insurgents, terrorist groups) on the other hand are not beholden to any law. To me, this is another relevant distinction: Is the act itself one of terror or military necessity? And is the actor a governmental organization beholden to the law?
