All of the World War II experiments with mustard gas were done in secret and weren't recorded on the subjects' official military records. Most do not have proof of what they went through. They received no follow-up health care or monitoring of any kind. And they were sworn to secrecy about the tests under threat of dishonorable discharge and military prison time, leaving some unable to receive adequate medical treatment for their injuries, because they couldn't tell doctors what happened to them.
Army Col. Steve Warren, director of press operations at the Pentagon, acknowledged NPR's findings and was quick to put distance between today's military and the World War II experiments.
"The first thing to be very clear about is that the Department of Defense does not conduct chemical weapons testing any longer," he says. "And I think we have probably come as far as any institution in America on race. ... So I think particularly for us in uniform, to hear and see something like this, it's stark. It's even a little bit jarring."
