Leaders at all levels are responsible for preserving the psychological health of their Marines, Sailors, and family members, just as they are responsible for preserving their physical health. This responsibility applies to every link in every chain of command from fire team leaders and work center supervisors to combatant commanders and commanding officers. Medical, religious ministry, and other support personnel can help with this task, but only line leaders can balance combat and operational requirements that expose warriors to risks with the imperative to preserve health and readiness.
