Are there any current, or Cold War-era, Royal Air Force helicopters fitted with skids as standard?
I seem to recall hearing, when I served, that RAF helicopters only ever had wheels, whereas skids were the exclusive preserve of the Army Air Corps.
This related answer says that the choice "seems to be that they are chosen based on the mission profile of the helicopter as well as the size to some extent." But, in my experience, both the RAF and the AAC support infantry operations in fairly equal measure, and the RAF Wessex and AAC Lynx have fairly similar weights.
