Which of the following is not considered an Information Operations (IO) discipline?

The correct choice highlights that Suppression of Enemy Air Defences (SEAD) is not classified as an Information Operations discipline. SEAD is primarily a military strategy and tactic aimed at neutralizing or destroying enemy surface-based air defenses to ensure air superiority for friendly forces. This concept is heavily grounded in operational military engagements and does not directly involve influencing or managing information.

In contrast, the other options—Computer Network Operations, Public Affairs, and Operational Security—are integral to the broader field of Information Operations, which focuses on the collection, processing, and dissemination of information, as well as protecting and altering the information environment.

Computer Network Operations involve the use of information technology to conduct warfare through both offensive and defensive strategies. Public Affairs relates to managing communication with the public and ensuring that accurate information about operations and the military is conveyed, playing a crucial role in shaping perceptions. Operational Security involves the protection of sensitive information that could be exploited by adversaries, thereby preserving operational effectiveness. Each of these plays a vital role in the strategic management of information in military operations.
