istorically, thats always been the dubious pleasure - nay, the raison d'etre, even - of the non-commissioned/oik side of the house..
The difference is all the mong/chiseler's get promoted to SL and suddenly get vision's of grandeur and a career. In reality it's the first 'earned' promotion they have had and some think they are on the fast track to CDS! It is the equivalent to the 'oiks' Cpl a rank where you learn not to be a plank for the future
