 Oh, I'm sorry. That's our Deborah Lee. I'm a 74 Delta. I'm with 545th Transportation Company. And we're here today to conduct mass confidence training in the gas chamber. So as they go into the actual chamber, they go in and get the confidence that the mask is working. So if they don't feel anything, if they don't smell anything, that tells me that their mask is good to go and they gain that confidence. So if anything should happen, a chemical attack or anything like that, they have the confidence in their mask that it would work.
