 So basically our first 10 soldiers, we sent them through, they were in full mopgear, that way that they could go down the DCD line and kind of get a first-hand experience of what we would have to do. So once the individual leave out of the gas chamber or contaminated area, so you have three zones, you have a hot zone, cool zone, and then the safe zone. So the hot zone is where we end when we're fully contaminated. So as you go into steps, you go from the hot zone to the cold zone to the safe zone. So each zone you go to, you remove off a piece of garment. So you go to the first zone, you're going to remove your out of garment, right, and you move to the next zone, you're going to move your boots and move on to the cool zone. You do the whole decontamination, they check for any type of radiation that you may have, and then from there you move on to the safe zone. We sent about six different iterations through in just their regular uniform and their masks just to test basically their confidence as far as how they feel in the mask, if they have a really good seal, that way if they're ever in a situation where there's an attack and they need to don their mask, they know how to do it properly and they know that they're safe. They have them take their mask off just so they can feel the difference and then we send them through the exit. I think it's a great learning experience. At least we know what we're getting into if we actually get hit with the real deal and come back to give you a real live experience of what extra gas can do to your body.
