Which of the following is not an effective tactic when handling civilian populations?

Ignoring the presence of civilian populations during military actions is not an effective tactic because it can lead to a breakdown in trust and potential hostility between the military forces and the local community. Proper engagement with civilians is crucial for successful operations, as it helps to minimize misunderstandings and fosters cooperation.

Establishing communication allows for open dialogue, addressing concerns of the civilian population and aiding in conflict resolution. Avoiding unnecessary violence and aggression is essential in maintaining civilian safety and establishing a positive relationship, while engaging locals for support and intelligence can provide critical insights and enhance operational effectiveness. Therefore, neglecting civilian presence is counterproductive and undermines the overall mission objectives.
