One of the points of military boot camp, in the late 80s, was to inflict mass amounts of mental and physical stress on recruits to break their individualism in order rebuild a team mentality to benefit the United States. Everyone was “broken” by our Drill Instructor without apology. Everyone had to be broken down and rebuilt without exception.
The Drill Instructor’s job (at the time) was to make the weak of mind and body quit in boot camp; otherwise, they would fail the United States in combat. Just after the most grueling week of boot camp (week four or so), our Drill Instructors mustered us inside the barracks one morning. They roughed us up for thirty minutes or so by making us hold wooden rifles out and away from our bodies with an outstretched arm (in five- and ten-minute intervals). It hurt and the pain was real.
