In which aircraft sensor posture does the lead aircraft focus on the friendly force while the wing aircraft scans the objective?

The scenario presented describes a situation where one aircraft is tasked with ensuring the safety and awareness of the friendly forces while the other is focused on scanning the objective. This aligns with the concept of a neutral sensor posture. In a neutral posture, the lead aircraft is not actively engaging or seeking out targets but rather maintaining situational awareness concerning friendly forces. The wing aircraft, meanwhile, is able to maintain vigilance on the objective, capturing any relevant information. This coordination allows for a balanced approach to engagement and awareness, prioritizing the safety of friendly forces while still monitoring the operational environment.

In contrast, the other postures typically involve more aggressive or defensive maneuvers. An offensive posture would imply actively seeking and engaging targets, while a defensive posture is focused on protecting one's own forces from incoming threats. Thus, the characteristics of the neutral sensor posture make it the appropriate choice in this context.
