Corpsman and combat medics often get tasked with being quasi-detectives before, during, and after coming in contact with the enemy. Due to the Geneva Convention and a special oath we take, we’re bound to treat every patient that comes our way — regardless of what side they’re on.

After every mission or patrol, the infantry squad gathers to conduct a debriefing of the events that transpired. It’s at that moment that thoughts and ideas are discussed before the squad breaks for some decompression time.

If the corpsman and combat medic took care of an enemy patient and discovered new information, everyone needs to know — the info could save lives down the line.

So, what kinds of things do we look for outside of the obvious when we treat the bad guys?

1. The importance of elbows.

Ask any seasoned sniper, “how are your elbows?” He’ll probably tell you that they’re bruised as hell. Many snipers lose superficial sensation in the bony joint after spending hours in the prone position, lining up for that perfect shot.

When a Taliban fighter has sore or bruised elbows, chances are they took a few shots at allied forces in the past. The squad doc can usually check that during a standard exam.

2. Scars are telling.

The Taliban are well known for seeking American treatment for minor issues, but typically go to their own so-called “doctors” when they get shot. Medical staff commonly search for other injuries while conducting their exam. Scarring due to significant injury is immediately red-flagged.
