I'm Getting The Credit For Something I Don't Deserve

I joined the military out of fear of being homeless. I get assigned to being a medic. On base everything is like a nurses assistant, then I get deployed. On my first mission I fail completely. I get discharged for it. I get a job in construction, this guy gets caught up in a winder. His arm is cut up, I tie a tourniquet on him, the ambulance takes him. Later my supervisor tells me that I saved his life. I didn't the EMT did, and the ER at the hospital. All I did was use a tourniquet, which may not have even been the right thing to do.
