The Bio/Chem Threat
Since the devastating attacks of September 11, the American public has become increasingly concerned with the threat of biological and chemical attacks: gas masks have become hot sellers, as have antibiotics rumored to combat anthrax.

The military on the other hand has been preparing to combat biological or chemical threats for close to a decade. Each service branch has trained Chemical-Biological teams, for instance the Army's Chem-Bio Rapid Response Teams (CB-RRT) and the Marine Corps' Chemical and
Biological Incident Response Force (CBIRF), to respond if the US was ever exposed to these types of weapons. If an attack occurred and the military was mobilized in response, these teams could provide tactical support to the civil authorities, advising them in ways to deal with the threat. Meanwhile, the National Guard could deploy one of its 32 Weapons of Mass Destruction Civil Support Teams (WMD-CST) to liaison with local authorities. So far, only ten WMD-CST's have been certified, one of which deployed to New York immediately after the Sept. 11 attacks.

The threat is real, but how likely are we to being exposed to biological or chemical weapons? And which ones should we be most worried about?
