You can't get on me for being contrary towards citation when you didn't even read it. What you were stating wasn't even in the ballpark of what the studies were suggesting, and you would have known that if you read the articles.
The only difference here is that I'm not making a bunch of statements of how things work, pretending that I know what I'm talking about like everyone else seems to love doing.
The things I know is that if someone goes through the same training and qualifications that everyone else does, they should be fit for combat. I know there are civilians on the front lines and it's common knowledge a part of a soldier's job is handling civilians. forget, one of the most vital things to an operation usually is a translator.
