Drill Instructor- The meanest sumbitcth you will ever meet. Only one branch in the US Armed Forces uses the term Drill Instructor and that is the Marine Corps they are your motivator and will do what ever the hell it takes to break you down and turn you into a lean mean killing machine. Never call a Drill Instructor "Drill Sergeant" or you will be signing your death warrant. They may be mean but apparently there the nicest guys after graduation. I wouldn't know since I am only a simple poolee who has actually reached PFC but hasn't gone to boot camp. Also kown as DI's and R. Lee Ermey.
That Drill Instructor made that one Recruit shit himself by doing PT because he wore his cover indoors.

This prison in Colorado offers teen offenders a second chance before big boy jail by indoctrinating them in a week long boot camp in which prison guards act like the Drill Instructors and change these wannabe thugs too fine young adults.
