Which aircraft sensor posture is when the lead aircraft's responsibility is the friendly force, and the wing aircraft is responsible for sanitizing the route directly in front of the friendly force?

The correct answer is based on the understanding of aircraft sensor postures and their specific roles in relation to friendly forces and threats. In a defensive posture, the primary focus is on protecting and ensuring the safety of friendly forces.

In this context, when the lead aircraft takes on the responsibility for the friendly force, it implies that its primary mission is to keep watch for threats or hazards that could endanger those forces. Meanwhile, the wing aircraft’s role in sanitizing the route directly ahead involves actively searching for any potential dangers, thereby enhancing the safety of the friendly units. This behavior is a hallmark of a defensive strategy, as it prioritizes the protection of one's own troops and prepares to counteract any threats in the operational environment.

This collective approach is essential for maintaining mission integrity and safeguarding forces from hostile actions, aligning perfectly with the principles of a defensive sensor posture where awareness and caution are paramount.
