What does an effort to "Counter-reconnaissance" typically target?

Counter-reconnaissance specifically aims to disrupt or thwart enemy surveillance and intelligence-gathering efforts. It involves actions taken to protect friendly forces from being observed or discovered by the enemy, thereby preserving operational security. By targeting the enemy's surveillance methods, forces can limit the information the enemy gathers about their movements, capabilities, and intentions, thus giving them a strategic advantage.

While the other options are related to military tactics, they do not specifically focus on the goal of counter-reconnaissance. Enemy formations pertain to the organization of an opposing force in battle, friendly maneuvers involve the actions of one’s own forces, and terrain obstacles relate to physical features that can affect operations rather than the intelligence activities of the adversary. In contrast, counter-reconnaissance's central role is to safeguard against enemy observation and inform the command of potentially hostile reconnaissance activities.
