In the military, the term "tent city" usually refers to temporary living quarters erected on deployed military bases, such as those found in Bosnia or Iraq. Depending on the branch of service and the length the tent city has been in place, the living space may have most modern amenities. For sanitary reasons, military tent cities place toilet, shower, and laundry facilities at least 50 feet (15m) from living quarters. Also, tents are typically divided into clusters of 8-10 to prevent the rapid spread of fire, which is of utmost concern because of the tent and bedding materials.
