11-12. Most often, Army commanders will be faced with deciding when and where to employ military deception in support of tactical operations. The intent of tactical deception is to induce the enemy decisionmakers to act in a manner prejudicial to their interests. This is accomplished by either increasing or decreasing the ambiguity of the enemy decisionmaker through the manipulation, distortion, or falsification of evidence. Military deception undertaken at the tactical level supports engagements, battles, and stability tasks. This focus is what differentiates tactical deception from other forms of military deception. (See JP 3-13.4 for more information on military deception.)
