Barksdale airmen set up a chemical agent detection paper stand during an Ability to Survive and Operate exercise on Barksdale Air Force Base, La., May 11. The paper is used to detect nerve and blister agents in the area they are placed. The paper will change colors when it contacts a nerve or blister agent.
