I am a retired Sergeant First Class Army medic with over 20 years and many combat as well as non-combat deployments. As a NCO my main job was to teach mentor and develop Soldiers assigned under me. I have had various classes and training as to different ways of doing this and have even developed some of my own. The bottom line is that no matter what the delivery, classroom, environment, or education level of students the most important thing is to know what you are teaching.
