I really feel that this should be some sort of April Fools joke but it isn't.
I'm just off the phone with the Department of Industry and Science, Export Controls section. If you are taking any military equipment abroad you need an Export License. Fine, I hear you say, no plans to take a Chieftan tank anywhere - but NO, this also includes the NATO hitch on your otherwise completely civvy landrover ! - I kid you not - its actually mentioned as an example on their website.
It also covers that 50 year old Series 2A Ambulance you've converted as a camper, your Sankey trailer....and my watch.
Nuts.
