This week on NRA's Life of Duty Network, we take a look at 3 Echo 9; the men and women who serve as U.S. Air Force Emergency Management Specialists. These are the people who gear up in the Level A HazMat suits to take care of everything from major aircraft accidents to the ever-present threat of an offensive biological warfare.

"My wife doesn't have any fears about what I do," explains TSGT David Yeo, an Air Force Emergency Management Craftsman. "If something was going to go wrong then it was going to go wrong whether I mitigated it or not."

It's difficult to explain all they go through to prepare for these incidents. For a better understanding, click here to see the trailer and link to the full 3 Echo 9 video event.
