What actually happens to the human body when an explosion happens in close proximity?

560 views

Honestly, I’m watching a war movie and a dude got hit by an IED. It got me thinking though, and I don’t quite get what is the lethal factor in an explosion?

There always seems to be fire in the movies, and it’s clearly a lot of force. But my question is what ACTUALLY happens to (I guess anything) that gets hit by a large bomb/explosion from a play by play/physics situation?

I feel like this is kinda dark, but I just had one of those curious moments and felt like this was the appropriate place to ask

When I was blown up out on patrol, it was the blast concussion that effected me the most. I was inside an armored vehicle every time so shrapnel wasn’t an issue. Until it was. Only one of them was bad enough to “hurt.” Head ringing, bloody nose, possible shit in underwater . The injury that sent me home was a mortar that hit a truck outside of the trailer I was in. Shrapnel from that came through a wall and put a hole in my skull an inch above my eye. That experience was odd.

It felt like I got hit in the head with large piece of wood. My ears were ringing, I could hear everyone yelling get down. That’s about the only thing movies get right about blast. That brain confusion, the ringing, and the way you can hear but it sounds distant. I just stood there thinking wtf just happened. My body was in shock, I couldn’t feel shit, except numbness. Everyone looked up at me horrified, but impressed, pointing to my forehead. My hand didn’t even make it pall the way up before I noticed my arm was covered in blood…so was the floor. I walked over to the shop area and we waited until a medic could come. I was just chatting away as if it was nothing. Just another day where you have a two inch gap in your skin, exposing a hole a little less than an inch. Not sure if the piece of metal still lodged or the hanging flesh that drew everyones attention. Soldiers are a messed up breed of humans. After doc gave me some morphine, my memory kind of comes and goes. Not sure how much after that actually happened and how much I put together while talking with people after the fact about it. I honestly thought I would have more lingering effects.
