Serious. SH rearcrew do do a sterling job. I don't think I've said on here they haven't or don't. They do sometimes sound like they are trying to justify their existance though. I don't think they need to, to be honest.
As for the RAF looking towards the Army Air corps to see how you do business, why should they when the training system is already set up to produce a competent crewman for the Puma, Merlin or Chinook.
You've not grasped this idea of 'jointry' have you?
