Nobody was killed, but we had a few injured. Thankfully the brunt of it hit the MRAP in front of us. If it hit my vehicle (HMMWV, flat bottom) instead I probably wouldn't be here.
That was the first major operation on my first deployment, too. Hello, world!
My takeaway? Shit just got real.
We ended up stranded that night after the 3rd IED strike (our "rescuers" said it was too dangerous to get us). It was the scariest day of my life, but in similar future situations it was different. I still felt fear and the reality of the existential threat, but I accepted it. It was almost liberating. Strange.
I deployed for another year after that (to Afghanistan that time). After Afghanistan I left the Corps and started my company. Because if it fails, what's the worst that can happen? Lulz.
