No difference this side of the pond. Next to the dike that protect's the island from the sea. Is a dump with 30 million kg explosives. It was the most economical sollution and consist's of German ww2 leftover's.
And old English shit. Our army switched to buying American weaponary at a certain time. This went on untill 1968 and unlike most people who like to think of it as a purely ww2 dump. It is not, it went on long after the German trash was cleared.
Did I mention it is on the surface of the seabottom. Not even a layer of mud or sand to cover it up. So this shit has been corroding for atleast 50 year's in salt water, Proven fact as the concentration's of chemical's are measureable higher then natural during death tide.
Assholes!
