The priority of effort goes to installation readiness and force health protection measures. Therefore, the installation commander ensures that the civilian workforce remains prepared, and commanders ensure their Soldiers receive flu vaccinations regularly. Post agencies develop plans to operate with reduced manning by prioritizing missions and ensuring that critical positions have cross trained replacements. Leaders stress inoculation of military personnel and develop plans to augment essential services. They also work with the installation to ensure that families are prepared for an outbreak.
