There are two elements of lethal-encounter attitude and mindset that often show up in conversation which I find somewhat contradictory.
One is the idea of being "calm". This is usually used to describe people who have seen battle over and over again and have become professionals at it through experience. There is a notion that calmness allows for efficient and correct execution of technique.
The other is the idea of being "violent". There's a lot of talk about "getting violent enough quick enough", with emphasis on an unspoken understanding of what it means to truly be violent. In some sense, I feel that this is critically tied to being "emotional". To be as violent as possible, it would seem you need to get enraged, to a certain extent. Violence almost crosses the line into an emotional or psychological property. I imagine violence in ECQ situations manifesting itself in tensed muscles and rapid, strong movements.
In some sense, the emotional nature of the "violent" idea seems to be at odds with the picture painted when talking about the "calm" professional. Even in so far as how I picture their physical manifestations.
How are these reconciled? Are they reconciled?
I've slowly been coming up with my own answer, but I'm much more interested in hearing others'.
