Current and future land warriors operate in a group or autonomously. The necessity to observe and locate targets during
day, night and all weather conditions inspire developments of small, but complex handheld devices, which are able to
fulfill these tasks. Observation in daylight can be achieved by means of a visual telescope with high resolution. For night
operation a thermal imager is required. Navigation tasks can be fulfilled with a digital magnetic compass and a GPS
receiver. For measuring ranges to targets an eye-safe laser rangefinder is necessary. OPUS H, the newest member of the
ZEISS family of handheld navigational and targeting devices, combines all these functions in a light-weight instrument
and analyses all data to provide first hand information about potential targets to the soldier and his group with sufficient
accuracy for combat decisions.
