CSU is located at Fort Widley, Portsmouth, and is the South Coast's premier Close Quarters Battle (CQB) Airsoft skirmish site.

The site offers an unparalleled urban playing environment with multiple levels of subterranean and overground areas to challenge your reactions.

Fort Widley is six sided in layout and is symmetrical about a north-south axis. The east and west ditches are enfiladed by small, two storey demi caponiers whilst the main ditch is covered by a full caponier. The return angles of the gorge ditch are protected by small musketry galleries.
