The veracity of the idiom “those who can, do; those who can’t, teach” can be argued, but it is generally untrue in the military. Moreover, we should seek policies that ensure those who can, do teach and we should recognize excellence in this area.
The mark of true experts is the ability to teach their craft, in a formal setting or informally through mentoring. Not everyone has the non-technical skills needed to teach in a classroom environment. Effective teaching requires communication skills, understanding of the learning process, comfort in public speaking, and many other attributes. Military professionals who display the necessary technical and teaching skills should be encouraged to pursue training and education opportunities that are (unfortunately) less common today than before the Revolution in Training (RiT) began in 2001.
