Well what are they? I am led to believe that their is no difference at all these days, an LE will still need to do a two week knives and forks course at Sandhurst and when commissioned they'd have do the same MK courses as a DE. Is it different for PQO's? I'm too just old for DE but I guess the rules would be bent for a PQO but obviously an LE would get me an higher rank (but I could probably complete PQO before I hit the required rank for LE). I don't intend moving from where I am but works taking up an increasing amount of time, a specialist (PQO) might be a better alternative.
