Re The Netherlands:
Apart from the Westland Lynx of the Dutch Navy ALL military helicopters in "Cloggyland" are operated by the Air Force. And that includes the Chinook.
Worse still: when all Lynx helos are replaced by NH90s in a couple of years time (first one about to be delivered!) the "Marine Luchtvaart Dienst MLD"/Dutch Naval Air Service will be merged into some sort of "Joint Helicopter Command" just like the Swedes and the Belgians have now.
