The Emergency Support Function (ESF) #3 Field Guide provides the US Army Corps of Engineers with information on tools and initiatives to improve disaster response and recovery operations. The Field Guide serves as a readily accessible resource with information for the civil emergency responder. It contains checklists, fact sheets, policy memos, and other materials, and is an essential tool for disaster response operations under the National Response Framework. It's also designed as a training guide to provide a base knowledge for future response and recovery operations. The Field Guide is updated every two years. The 2015 ESF #3 Field Guide is the most recent version. To request a hard copy of the 2015 ESF #3 Field Guide and/or pocket guide, please contact the Readiness Support Center at (251) 694-3601.
