Greys Anatomy called, they want their episode plot back
The pressure that surgeons are under to ensure their patients survive is huge but this surgery had the risk of killing everyone in the room if the surgeon made a mistake. >

How does a grenade... that hasn't exploded... get logged in someones chest? >

Grenades from rifle-mounted grenade launchers must travel a minimum distance before they arm themselves. It is possible that this soldier took a grenade shot at point-blank range while the grenade still had enough energy to penetrate flesh but before it armed itself.
Edit: the exact numbers depend on the type of grenade used, but a Russian Vog-25 grenade weighs 250 grams and travels at around 250 feet per second muzzle velocity. Minimum arming distance can be as low as 33 feet.
A steel grenade with that speed and mass could easily have enough energy to penetrate right into your soft bits and break whatever bones get in its way. Honestly, if it didn't hit bone at all, I wouldn't be surprised to hear about one punching straight through someone's abdomen. >

That’s probably what happened. I recall seeing a video in… I think it was Iran? A protestor was hit by a smoke grenade shot from a grenade launcher, and it embedded itself in him and knocked him unconscious. I recall reading he survived somehow, but that could be misinfo >

I've seen the idf do that to people in Israel in videos. >

Survived a real life noob tube attack. Good job on everyone in that medical team. >

I feel like "Unexploded" is a given, here. >

One time, my dad removed a penny from behind my ear, so I understand what this guy is going through.
