Over half of all injuries to U.S. troops are due to explosions, and a large percentage of those are head injuries. While helmets offer some protection, explosive pressure waves can be transmitted to soldier’s brains via their unprotected faces. With this in mind, researchers from the Massachusetts Institute of Technology (MIT) have created a computer model to evaluate how useful face shields on army helmets would be in reducing traumatic brain injuries. Their conclusion: shields could save lives.
