What are the two types of beacons containers used in the marking set?

• A. Red and Blue
• B. White and Infrared
• C. Green and Yellow
• D. Black and White

Answer: (B)

Beacons in a marking set are designed to be detectable under different visibility conditions. One type emits white light, which is visible to the naked eye and useful during daylight or when observers are nearby. The other type emits infrared light, which isn’t visible without specialized equipment like night-vision or IR sensors, making it ideal for nighttime marking without giving away position to those without IR gear. Using both types ensures the marking set can be read across a range of conditions, from day to night. That blend—white for general visibility and infrared for covert nighttime use—is why the correct pairing is white and infrared.
