from the blimp balloon system, and later evolved into other platforms, including fixed towers and relocated masts, which addressed logistical issues tested while on deployments. Operational impact Considering the majority of casualties in both Iraq and Afghanistan in terms of the Global War on Terror were from improvised explosive devices (IEDs), the need for surveillance has increased with their increased use. In a move to counter this threat and lower the effectiveness of IEDs, the US Marine Corps directed the creation of a persistent surveillance system to identify and counter threats to security of military installations. The Marines requested the system be fielded as soon as possible. The result of this request was the development of the Ground Based Operational Surveillance System ready for rapid deployment to theater. The G-BOSS provides the command operations center with a round-the-clock display and tracking of items of interest through the use of high resolution night and day cameras. The cameras are integrated with enhanced target recognition and radar systems used to increase the ability to detect moving targets. The G-BOSS allows personnel to counter insurgent activities with an emphasis of disrupting placement of improvised explosive devices. The G-BOSS enhances situational awareness by allowing personnel to monitor activities in the vicinity of the military installation. Common places of surveillance include the gates, along the roads, borders, rivers, pipelines, and chokepoints, among other areas of responsibility and interest. The multiple towers of cameras and surveillance systems allows for 360-degree security with easily understood computer displays. Included on the computer displays are alarms and assessment data through overlay and window pop-ups, with 24/7 network running capability, allowing reduced manpower and hours in relation to personnel on guard. The multiple camera systems have the capability of routing all into a single remote ground system. The Marine Corps Operational Test and Evaluation Activity, (MCOTEA), conducted operational tests on the G-BOSS with a simulation of the how to employ it in relation to situational awareness. From the testing of the G-BOSS, it was concluded that the most critical factor in enhancing its operational effectiveness is the positioning of the towers. The G-BOSS is best utilized in open terrain, which employs better dispersion and better performance. The tests utilized role-players and stealth techniques of insurgents to test the intuitive nature and helping to identify attempts to mask hostile intent. The key is to increase the G-BOSS operators’ training and vigilance
