The Clip-On Ruggedized Advanced Thermal Optical Sight (CRATOS) is a miniaturized all-in-one thermal weapon sight designed for handheld, clip-on or stand-alone use. The thermal imaging capability of the CRATOS allows for observation and target identification under adverse conditions, including light rain, smoke, light snow, and low light to total darkness. Its integral laser pointer allows for handoff of target positions to the warfighter with night vision goggles.
