Oh,
For starters, while the Chinook's
main task is to support the British Army, it's not the Hook's
only role -- vis. the recent humanitarian air drops in support of the Yazidi refugees, and the type's use as a general (as opposed to British Army-specific) CASEVAC platform in-theater. Not to mention its support of the Royal Marines (incl. shipborne ops):
I leave the question of whether the RAF
should operate RW assets to those better in the know.
