Westover it still an active military base so we will only provide information on those portions of the facility that are abandoned or not longer used for military purposes such as the former Stonybrook nuclear weapons storage area.
Pillboxes such as this one (below) were manned by soldiers with machine guys when nuclear weapons were being worked on/transported. Access to the bunker was via underground tunnel.
The images below are not all from Westover/Stonybrook but they are representative of the type of security used by weapons storage areas.
This type of fencing was used at USAF Weapons Storage
Areas.
