Hush. We are discreetly different forces that attract different people. Most of the time we also do different jobs. You'll be calling for the same uniform next. Some of our training is the same, some of it similar. However, I joined the RAF and proud of it. I made a positive decision to join it and not either of the others. The changes (erosion) would have to be pretty big to put us all in together at that stage - it would just end up as 3 seperate training facilities co-located or (more likely) the Army would bully us all into doing it their way!
