What is a Noise-Flash Diversionary Device (NFDD)?
A Noise-Flash Diversionary Device (NFDD), commonly referred to as a flashbang, is a non-lethal explosive device used in tactical situations to temporarily disorient a target’s senses. The device produces a loud noise (about 170 decibels) and an intense flash of light (over 1 million candela) when detonated. This combination overwhelms the target’s hearing and vision, causing confusion and distraction, which is crucial in law enforcement and military operations.
NFDDs are commonly used in situations that involve high-risk entries, such as SWAT team operations, hostage rescues, and raids. The purpose of the device is to create a diversion that gives tactical teams a few seconds of advantage to enter a room or control a situation with reduced resistance. While NFDDs are designed to be non-lethal, improper use or deployment in close proximity can still cause injury.
In firearms and tactical training, familiarity with NFDDs is important for operators to understand how to use them effectively and safely. Training focuses on the timing and placement of the device to maximize its impact without endangering personnel or bystanders.
