What is the maximum range of the AN/TAS-4B Night Sight (DISMOUNTED)?

• A. 3,000 meters
• B. 2,000 meters
• C. 4,000 meters
• D. 5,000 meters

Answer: (A)

The key idea is that maximum range for a night sight is a spec value set by the device’s sensor and optics under standard conditions. The AN/TAS-4B Night Sight (Dismounted) is specified to detect targets at up to about 3,000 meters. That means, in clear air with typical target contrast, you can expect to notice a target silhouette at roughly 3 km. Real-world factors like weather, smoke, rain, and the target’s size or thermal contrast will reduce that distance, so practical engagement ranges will be shorter. The 3,000-meter figure is what the manufacturer lists as the device’s maximum detection range for this dismounted configuration.
