At Fort Campbell in Kentucky, spouses of U.S. soldiers headed to Liberia seem to be lingering just a bit longer than usual after predeployment briefings, hungry for information about Ebola.

For these families, the virus is raising a different kind of anxiety than the one they have weathered during 13 years of ground war in Afghanistan and Iraq. They want to know how the military can keep soldiers safe from the epidemic, a new addition to the Army's long list of threats.

"Ebola is a different problem set that the division hasn't (faced) before," said Maj. Gen.Gary Volesky, who will soon head to Liberia along with soldiers from the 101st Airborne Division.
