I love how focused he is on the weapon as it comes out of his buddy in the firsy gif scene. It looks like he is assessing the damage based on how the blade looks which is super super smart. It is not a matter of whether they guy was stabbed or not but how deep the stab is to determine the severity, and a good way to quickly measure that is like a dipstick on the car to see where the line of blood starts on the blade. And in that scene it looks like he is doing that right away, before anyone else in the scene even understands what has happened yet. Joe is all over it. Super solider.
