B hut

The British Army commonly used the term "Barracks Hut" to refer to temporary billets as far back as the 1800s.

It is suggested, not confirmed, that the term B-Hut/Barracks Hut was carried over in vocabulary from British occupation and influence in Afghanistan during the early 1900s.

It is cheaply made (US Gov't cost of about $15,000 each at time of construction)[1] of plywood and divided up into separate rooms with a common walkway down the center, or left open containing one large space.

A typical B-hut has two entrances, two or three fluorescent lights on the ceiling, a small ductless air conditioning unit above each door.

B-huts afford no protection from indirect or direct fire and are often ridiculed by the service members and contractors who reside in them, but they offer limited privacy to the occupants by allowing them to have their own rooms.
