Emergency Combat Medic from military. They don't cover much fixing though. Just stabilizing. They would say clean, staunch, wrap and transport.

Everything I just listed was from my own reading. I've actually practiced deep tissue stitches on some turkey breasts though. LOL. The hard part for me would be getting the supplies to do a procedure like I listed properly on the civilian side. I have my ECM bag issued to me but that's about it and they have next to none of the things I have listed above.

Dissolving suture material, saline wash, painkillers, anesthetic, and antibiotics are all VERY hard to accumulate on civilian side, especially in large quantities.
