When properly integrated with operations security (OPSEC) and other  information-related capabilities, deception can be a decisive tool in altering how the enemy views, analyzes,  decides, and acts in response to friendly military operations. For more information on Army support to  military deception see FM 3-13.4  2-98. OPSEC is a capability that identifies and controls critical information and indicators of friendly force  actions attendant to military operations and incorporates countermeasures to reduce the risk of an adversary  exploiting vulnerabilities. OPSEC identifies critical information and actions attendant to friendly military  operations to deny observables to the threat intelligence systems. For example, camouflage and concealment  are OPSEC measures and survivability operations tasks used to protect friendly forces and activities from  enemy detection and attribution. For more information on operational security see JP 3-13.3.  2-99. Military information support operations which are planned operations to convey selected information  and indicators to foreign audiences to influence their behavior and ultimately the behavior of their  governments. Selected audiences may include enemies, adversaries, unified action partners, and neutral  groups or populations. Psychological operations support forces devise actions and craft messages using  visual, audio, and audiovisual formats, which can then be delivered by air, land, and maritime means, and  through cyberspace, to selected individuals and groups. Many actions of the FS system, such as strikes, have  psychological impact, but they are not military information support operations unless their primary purpose  is to influence the attitudes, rules, norms, beliefs, and subsequent behavior of a target audience. For more  information see JP 3-13.2.  2-100. Fire support requirements should be deconflicted and synchronized with special technical operations  (referred to as STO). Detailed information related to special technical operation and their contribution to fire  support can be obtained from the special technical operations planners at combatant command or service  component HQ.
