Back in the days when I used to be a techie on the Harrier force in Germany we were on deployment in the field in Denmark. Every night when we were debriefing late into the night the brave harrier pilots would complain in the morning about the noise. Come the weekend when the techies were on guard duty the pilots were making a hell of a noise without any care for anybody else, about an hour later they all dissapeared, this is when our team chief went for a walk with a shovel. We didn't know what he had done until 4.00am when all hell broke lose in the pilots tent. They had climbed into their sleeping bags only to find the contents of the local protected ants nest in it with them and the ants weren't sleeping.
