Therefore, leaders at every level review the RUF with their subordinates as part of their pre-mission inspections and confirm that the Soldiers know the rules. Commanders should obtain and issue a rules for the use of force summary card to each Soldier before deploying from home station, and small unit leaders should inspect to ensure that the Soldiers have it.

Above all, unit leaders must understand if, when, and how they may use lethal force to protect a facility or to save lives.
