I often think that a sharpshooter must be the calmest and most focused person.
The Reconnaissance Platoon of the 601st Brigade is a small unit in the Combat Engineering Corps. Earlier this year, they held an exercise in a densely wooded area, where they practiced combat fighting, reconnaissance and evacuating injured soldiers. They also practiced fighting underground.
But I think what they needed to practice most was the Zen of sharpshooting.
