Chapter II - Domestic CBRN CM (4) Considerations: (D) Organizing Considerations: (3) Joint Planning Augmentation Cell (JPAC): The JPAC is a tailored group of CBRN response joint planners. The cell is manned, equipped, and trained by JTF-CS to assist other JTF staffs or the DCE. JPAC members maintain currency in CBRN areas through professional education, participation in joint and multiagency exercises, and through planning for national special security event contingencies. The JPAC is able to focus an ad hoc JTF staff on how to employ joint forces in conducting CBRN response. The JPAC also assists the JTF with obtaining technical augmentation or dedicated reachback capability from DTRA, United States Army Medical Research Institute of Infectious Diseases (USAMRIID), United States Army Medical Research Institute of Chemical Defense (USAMRICD), United States Army Forces Command's (FORSCOM's) 20th Support Command, and the CDC. These experts maintain liaison and reachback capability for the JTF and JPAC to nationallevel expertise, while providing on-staff subject matter expertise. The JTF medical officer, in particular, should consult with these technical experts, as they are able to provide information critical to medical planning considerations
