Perfume at War: Odor as Sword and Shield

The use of vision and audition in stealth applications is well recognized; however, other perceptual senses can also play a valuable role. This volume discusses the sense of smell (olfaction), its use in nature and everyday life, and its potential applications in military and stealth operations. The sense of smell has largely been overlooked and underutilized in warfare, being restricted to crowd control and deterrent applications. However, the olfactory dimension can be a promising addition to other Department of Defense applications, such as stealth operations, deception, misdirection, and force projection. Further research into olfaction is needed to achieve these aims.
