The Pentagon has been playing catch-up with veterans exposed to chemical agents in Iraq, and the numbers involved just increased exponentially. The New York Times reports that 629 members of the US military since 2003 have reported exposure during their tours of duty—not from attacks but from encounters with abandoned arsenals.

Jordan Zoeller, who has suffered health problems since his exposure in 2008. "They were like, 'Oh, that never happened.'"
