Identification with a video sight

In a hard splinter environment the future soldier might need the ability to observe and fire from cover. He than has to use indirect observation. To map the difficulties going from direct visual observation to indirect video presentation of the surroundings five experiment have been conducted. A total of thirty observers have judged whether soldiers and civilians have been armed in close and open country, what the type of display means to the judgements, what magnification is needed to judge armament at a typical tactical distance, at what distance it is possible to identify representative small arms and how well a car registration number can be read. The observers have made early uncertain judgements, based on vague information, as well as certain judgements. Human natural behavior, e.g. swinging with the arms and turning the body, have facilitated the formulation of early well-founded hypothesis. Certain judgements have sometimes demanded high magnification and the difference between displays can be considerable.
