What is Chaff (countermeasure)?
[[File:Usnchaff.jpg|thumb|Chaff in its containers and loose]] In the [[military]], '''chaff''' is a bundle of small thin pieces of [[metal]] which are shot out of an [[airplane]] or [[warship]]. These thin strips of metal spread out to make many reflections for enemy [[radar]] to detect instead of the target. The many reflections also make it harder for [[radar-guided missile]]s to hit anything. The chaff tricks the enemy and helps to keep the plane or ship or other target safe. Chaff was invented during [[World War II]]. Later radar methods made it less effective but chaff is still used because it is cheap and simple. [[Category:Weapons]] {{military-stub}}
