One of the ways an IED injures people is through the effects of blast, and so medical and defence researchers are working hard to understand these effects. Because some of that research is being done here at CFB Suffield, I was interested in this article in the Globe and Mail:

They have no visible signs of injuries, no head wounds or burns. But soldiers who are nearby when an improvised explosive device detonates may suffer mild brain damage, new research suggests.
The shock wave produced in this type of explosion can travel through the brain and cause a concussion, also known as a mild traumatic brain injury, says Andrew Baker, a researcher at St. Michael’s Hospital in Toronto.
