Barracks are military housing. Often times NCOs and enlisted personel will be housed in barracks for service or training. Lower level NCOs will be housed in larger numbers where as higher ranking NCOs or officers will be housed in fewer numbers.
History of Barracks
There are a number of remains of Roman army barracks in frontier forts such as Houseteads and Vindolanda. From these and from contemporary Roman sources we can see that the basics of life in a military camp have remained constant for thousands of years.
