One of the things that I have learned from RumRation is that, due to differences in the various entry requirements for different branches, the Logistics officer specialisation is massively over-subscribed. This means that not only do prospective Logistics officers have to pass their AIB, but they have to get a very high pass mark to gain one of the few places at BRNC. Why then, given that they must be the 'creme de la creme de la creme' do they often seem to be lacking in some areas. The chap on Turbs who was on Quarterlies is not, in my experience, in a small minority. Yes, I have known Engineer and dabber officers who have struggled, but in nowhere near the same proportions as the Logistics branch. So, what is wrong with the system that the best junior lieutenants on board are invariably not the LO? Is it, as someone suggested to me, that the majority of submarine LOs are not volunteers, but the gash that the General Service wants to ditch? Is the AIB itself failing to pick the right candidates due to an embarrassment of riches?
