Virtual battlefield. Image depicting the use of virtual reality (VR) in the military. An officer is seen wearing a VR helmet. He is able to 'pick up' circles depicting landing zones or military objectives and place them on a virtual map of a battlefield, thus giving orders to units as to where they should move. The display also includes 'floating' screens showing real-time views of various elements of the force available; such as aircraft (left), ground forces (centre) or airborne Marine forces (right). The terrain data are generated from digital maps and real-time reconnaissance information.
