Totally agree. We've proved that we can have a standardised joint pilot course so why not go the whole hog and do the same with rearcrew.
It may lead to us having a 'pool' of correctly trained guys who, with just a CTT/OCU, could fit into any role within JHC. Now there's a thought! We could even do it with pilots! Why can't Army SNCO pilots exchange on Puma, Chinook or Merlin?
Flexibility.
