  THREATS
  1-34. For every operation, threats are a fundamental part of an OE. A threat is any combination of actors,
  entities, or forces that have the capability and intent to harm United States forces, United States national
  interests, or the homeland (ADP 3-0). Threat is an umbrella term that includes any actor with the potential to
  harm the United States or its interests. Threats include—
  * Enemies.
  * Adversaries.
  * Peer threats.
  * Hybrid threats.
  * Insider threats.
  1-35. An enemy is a party identified as hostile against which the use of force is authorized (ADP 3-0). An
  enemy is also called a combatant and treated as such under the laws of war. Enemies will employ various
  advanced technologies to attack Army forces in cyberspace and EMS to disrupt or destroy the ability to conduct
  operations or collect information that will give friendly forces a strategic, operational, or tactical advantage.
  1-36. An adversary is a party acknowledged as potentially hostile to a friendly party and against which the
  use of force may be envisaged (JP 3-0). Though an adversary is not treated as a combatant, the goal is still to
  prevent and deter conflict by keeping their activities within a desired state of cooperation and competition.
  1-37. A peer threat is an adversary or enemy able to effectively oppose U.S. forces world-wide while
  enjoying a position of relative advantage in a specific region (ADP 3-0), including cyberspace and the EMS.
  Peer threats often have cyberspace and EW capabilities that are comparable to U.S. capabilities. Peer threats
