Spc. Zachary Nickles feels the effect of CS gas after going through the confidence gas chamber. The confidence chamber is designed to give Soldiers confidence in the protective mask should they ever need to don their mask. Nickles won the Best Warrior Competition and will represent the 807th at the US Army Reserve Best Warrior Competition in Fort Dix, N.J., in June.
