non-profit organization set up to support the families of fallen paramilitary officers. The name refers to the motto of CIA's Special Activities Center: Tertia Optio, the President's third option when military force is inappropriate and diplomacy is inadequate. TOF provides comprehensive family resiliency programs, financial support for the families of paramilitary officers killed in action, and it works behind the scenes to "quietly help those who quietly serve."
