A simple enough challenge I suppose, how many have put up a 12x12 tent (Not many I can tell you). So what's the catch....... nothing !!!
All you have to do is unpack a standard green UK Forces 12x12 tent put it up and then take it down again .... Oh yes and re-pack it all within 15mins ( I knew there was a catch somewhere).
So get your local regular forces unit to loan you a 12x12 tent for a weekend and get practicing.
