The portability of the Quonset hut made it especially useful to the United States Army back in World War Two. At that time, the Quonset hut was used for every building need on the base, from barracks to post office to medical post. Though as the troops kept marching the Quonset huts could be packed up to be taken to the next location. The same still goes today, meaning that when you are done with your Quonset hut at a certain location you can move it to where it is needed most. It is much easier to ship then other buildings and it means you do not have to build a new one.
