In my day, which was a very long time ago. there were TWO KNOWN FACTS.
First Fact: if you locked a British Infantryman in a padded square room that had no windows, no doors and no furniture in it; you then put into the room the latest and most expensive bit of equipment ever made; one of three things would happen.
ONE: He would lose the bit of equipment.
TWO: He would hurt himself with the bit of equipment, or
THREE: He would break the bit of equipment.
Second fact The British Infantry man is the best soldier in the world! Ask Wellington or Slim.
