Hesco hobbit
n.— «Kandahar Air Field is a Hilton by comparison, populated by what the frontliners call Hesco Hobbits, hescos being the two-metre-high buffers filled with gravel that surround the base.…And they wouldn’t mind if the Hesco Hobbits gave them some sympathetic respect when they come inside the KAF wire to experience real food, hot showers, flush toilets and the giddy joys of air-conditioning.» —“Canada’s finest revel in life at the end of the world” by Don Martin National Post June 29, 2007.
