The most common tent uses for the military are as temporary barracks (sleeping quarters), DFAC buildings (dining facilities), forward operating bases (FOBs), after action review (AAR), tactical operations center (TOC), morale, welfare, and recreation (MWR) facilities, and security checkpoints. Furthermore, most of these tents are set up and operated through the support of Natick Soldier Systems Center.
