The analysis of the shooting accuracy showed the homogeneity of the subject group. In mean three shots were placed in an area of 3.66 cm x 3.66 cm (SD: 2.35 cm²) regardless of the tasks, phosphor color or the position in the course. The accuracy of the fire using NVG were regardless of the phosphor color high significantly better (p = 0.00034 green resp. p = 0.00014 white) than in daylight conditions. However, the use of the aiming laser equipment attributes probably for this and it is not a true performance criterion. No significant difference was found between the three groups in the passthrough time (p = 0.89). As well no difference was found in respect of the accuracy of fire between the different screen color of the NVGs (p = 0.56). The soldiers self-assessment revealed with high significance (p = 0.001) a preference to the NVG with the white phosphorus screen.
The soldiers probably prefer white phosphor because it looks closer to daylight. In contrast to this subjective preference, no significant objective performance differences appeared when using NVG with either white or green I² phosphor.
