Nearly 600 Army and Air National Guard forces from New Jersey and New York are preparing for the worst.
They are participating in a homeland response force drill at New Jersey's Joint Base McGuire-Dix-Lakehurst on Friday.
The troops specialize in rescue, security, decontamination and medical treatment.
The units will train to rapidly assess and identify a chemical, biological, radiological or nuclear incident.
