Did my time at the Benning School for Boys some years ago. Laerned how to swear at malfunctioning weapons and eat red dirt. Back then, and it may be true today, an EM could NOT be busted below E-2 "E Duce". A "Speedy Four" is, in officer paralance, a Specialist 4th Class. Retraining after the cofffee break was sometimes required.
