As part of this study, conduct a blast surveillance program to monitor, record, and maintain data on blast pressure exposure for any soldier, in training or combat, who is likely to be in a position where he or she may be exposed to blasts.Expand on existing blast pressure monitoring in training and establish a longitudinal medical study on blast pressure exposure during combat and training in order to better understand the relationship between blast pressure exposure and brain injury.Improve understanding of blast-induced brain injury The Army should increase its efforts to protect soldiers against blast-induced brain injury, with increased resources for testing, experimentation, and combat helmet development. In the longer term, new materials and technologies could be used to mitigate the blast wave through improved helmet design or off-board protection from robotic teammates.In the near term, computational modeling and physical experimentation can be used to assess various existing helmet designs and their response to blasts of various sizes and locations. ![]()
