Traumatic Brain Injury from multiple IED blast to vehicle in combat, vehicle was destroyed and inoperable and multiple people in same vehicle as me lost their lives . I was knocked out on several occasions from concussion and being within feet of blast sight. Initially was issued faulty earplugs in 2003  and would bleed from ears after being within correct training perimeter guidelines but discovered faulty manufactured earplugs were to blame. Most notable accidents were from vehicle being hit by many different types of roadside bombs in which the vehicles I was riding in were damaged and on 4 occasions the vehicles were obliterated and I had either been ejected or buried in rubble or both. 9 people were killed in my vehicle over multiple  occasions from these blast that obliterated the vehicles. Driving on some of these roads were terrifying. Sometimes I see something on the road and I just can't take it. Sometimes it takes me a few weeks to get back in my truck annd drive.
