British Army Issue "Fishing Chair"

Similar to the British Army Issue Folding Chair, this "fishing chair" was actually manufactured for and issued to the British Army. We've been racking our brains over here at Swiss Link trying to figure out what the Brits need a fishing chair for, but I suppose we shouldn't question any man's need for leisure. What sets this apart from the other chair? It has a cup holder. Yes, this is actually a piece of genuine military equipment.
