Before an event, the NDMS Special Purpose Emergency Augmentation Resource (SPEAR) leads final team preparedness efforts, providing a refresher on the specialized medical techniques and equipment that could be needed in the case of an emergency. SPEAR works with NDMS DMAT and National Veterinary Response Team (NVRT) to ensure a common understanding of certain key concepts in disaster medicine, enabling teams that come together from units across the country to work together more effectively.
