If you've never heard of a Defense Department organization called Joint Task Force Civil Support, that's understandable. And arguably, it's a good thing. JTF-CS may be the smallest task force in the military's force structure: its headquarters at Fort Eustis, Virginia, has less than 200 people working there, and it's main mission is to organize the military's response to a chemical, biological, radiological or nuclear attack in the United States. Our guest this week is Maj. Gen. Bill Hall, who became the commander of JTF-CS earlier this year. He says he's wanted to command the task force ever since he learned of its existence a decade or so ago. He talked with Jared Serbu about why that's the case.
