Büdingen Airfield, Büdingen, around 2003-2005
(Source: Phil Philipps, Germany)
The airfield is now used for some indoor unit events (in the hangar) and the outside space is used when the 1-1 Cav trains on simulators. Then the 6966th TTT (Civilian Support - most of the times) brings CCTT "Close Combat Tactical Training" trailers, those get linked together, and then they play "online games" or big battlefield simulations.
