Sgt. Noah Devoux, a chemical, biological, radiological and nuclear specialist with the 44th Chemical Company, 2nd Chemical Battalion, 48th Chemical Brigade, takes a sample of an unidentified liquid that was found in a lab of an abandoned hotel, June 12, 2013, during his unit's Defense CBRN Response Force training exercise, in Killeen, Texas. Devoux was part of a reconnaissance team that found a homemade mustard gas lab in one of the hotel's rooms. The team took a sample of the liquid so it could be analyzed to determine if it was hazardous. The 44th Chem. Co. has been designated as part of the Department of Defense's Defense Chemical, Biological, Radiological and Nuclear Response Force for this fiscal year, as well as next fiscal year. U.S. Army North (Fifth Army)'s Civil Support Training Activity-Central was on hand to provide training for the company before conducting their annual certification, which took place June 14.
