What action does the Flight Leader take when a new member joins the flight?

When a new member joins the flight, the Flight Leader's responsibility is to effectively integrate that individual into the team. The appropriate response is to return the salute of the new member and instruct them to "FALL IN." This action not only acknowledges the new member's presence and status but also facilitates immediate inclusion into the unit, signaling that they are now part of the team. Such a response promotes cohesion and a sense of belonging, which are vital in a training environment like Officer Training School.

The phrase "FALL IN" is a command that directs the new member to take their place within the formation, which reinforces the structure and discipline expected in military settings. This clear directive helps the new member understand their immediate role within the flight and establishes an atmosphere of teamwork and cooperation.
