Which of the following is a method to develop the leadership principle of knowing your Marines and looking out for their welfare?

The approach of correcting grievances and removing discontent is vital for developing the leadership principle of knowing your Marines and looking out for their welfare. This method emphasizes the importance of active listening and responsiveness to the concerns of team members. By addressing issues that may lead to dissatisfaction or unrest within the unit, a leader fosters an environment of trust and support.

When Marines feel that their grievances are acknowledged and acted upon, it reinforces their sense of value and belonging within the team. This not only strengthens the morale of the unit but also enhances overall cohesion. Knowing your Marines extends beyond just understanding their names or rank; it involves recognizing their challenges and providing the necessary support to resolve them. Thus, addressing grievances is a proactive way to demonstrate care and commitment to the welfare of each Marine, which is essential for effective leadership.
